Effect of em rays
Electromagnetic waves travel at the speed of light through space or a medium. The wavelength and frequency of these waves are inversely related by the formula f*λ = c, where f is frequency, λ is wavelength, and c is the speed of light. For a given medium, the speed of light does not change, so higher frequency waves have shorter wavelengths, and lower frequency waves have longer wavelengths. Electromagnetic fields are present everywhere and invisible to humans. Electric fields are created by voltage differences and magnetic fields are created by electric currents. Both decrease in strength with distance from their source.
wireless power Transmission
Wireless power transfer can transmit electrical energy without wires through near-field techniques like inductive coupling and resonant inductive coupling over short distances, or far-field techniques like microwave and laser beam transmission over longer distances. It has advantages of being convenient and reducing transmission losses but higher costs. Research is ongoing to improve efficiency and commercialize the technology for applications in consumer electronics, transportation, and providing energy access.
witricity
WiTricity is a technology developed by researchers at MIT that enables the wireless transfer of electrical energy between devices without wires. It works by using magnetic resonance between self-resonating copper coils, allowing power to be transmitted across short air gaps from a transmitter source to a receiver device. While the concept of wireless power transfer has existed since the 19th century, WiTricity could allow for practical and safe applications like wirelessly charging phones, laptops and other devices. However, more research is still needed to improve efficiency and develop commercial systems.

Microwave wireless power transmission
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite overhead conductors and underground cables that use high temperature super conductor. But, the transmission is still inefficient. According to the World Resources Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%,40% and greater than 40%. This is attributed to technical losses (grid’s inefficiencies) and theft. Any problem can be solved by state of the art technology. The above discussed problem can be solvedby choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.

An electromagnetic pulse (EMP) weapon called an E-bomb is proposed. It could destroy power grids, electronics, and communication systems over an entire coast while sparing humans and other living species.

While an effective weapon, E-bombs would be difficult to implement accurately and their effects hard to assess. Defenses would require comprehensive electromagnetic shielding.

wireless power transmission, wireless energy transmission, or electromagnetic power transfer is the transmission of electrical energy without wires.
Wireless power techniques mainly fall into two categories, non-radiative and radiative.
In near field or non-radiative techniques, power is transferred by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes.
In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves or laser beams.

wireless electricity report word docs
This document summarizes the history of wireless power transmission (WPT). It discusses how Maxwell's equations predicted radio waves in 1864 and experiments in the late 1800s provided early evidence of wireless transmission. Nikola Tesla conducted the first WPT experiment in 1899, but it had low efficiency due to long wavelength. Development of higher frequency microwaves in the 1930s allowed for more efficient concentration of power. W.C. Brown pioneered microwave power transmission research from the 1960s, including powering a helicopter wirelessly in 1964. Many laboratory and field experiments using 2.45GHz and 5.8GHz frequencies followed in subsequent decades, advancing WPT technology.

Witricity
Wireless electricity, also known as WiTricity, was first proposed in 1899 by Nikola Tesla. In 2007, a group of MIT scientists led by Marin Soljacic revived the concept and developed an efficient wireless power system. WiTricity works by using magnetic resonance to transmit electric current from a transmitting coil to a receiving coil within a few meters without wires. While it provides advantages like eliminating wires and batteries, challenges remain in improving efficiency and increasing the range of wireless power transmission.

wireless electricity seminar report
This document provides an introduction and history of WiTricity, which is a technology that allows for wireless power transmission without the use of wires. It discusses how WiTricity works using electromagnetic waves to transfer power over distances. The history section outlines some of the key discoveries and experiments that led to the development of WiTricity, including Maxwell's equations predicting radio waves, Tesla's early experiments with wireless power in the late 1800s, and experiments in the 1960s demonstrating wireless power transmission to power helicopters and transmit power over a mile. Today, WiTricity research focuses on increasing transmission efficiency and applications like powering mobile devices without plugging them in.
WiTricity - Electricity through Wireless Transmission
Wireless power transmission through resonance coupling was proposed over a century ago but recently rediscovered. It works by powering electromagnetic resonators at the same frequency so that energy transfers between their coupled magnetic fields, allowing devices to charge without wires. Researchers at MIT demonstrated this by lighting a bulb from a source over 2 meters away. Applications could include wirelessly powering devices, vehicles, and buildings to improve efficiency over transmission lines that incur large losses. While promising, wireless power systems require transmitters and receivers tuned to the same precise frequency for energy to transfer effectively over distances.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
