This document discusses wireless power transmission (WPT) and its history, mechanisms, applications and advantages/disadvantages. It describes how WPT works through electromagnetic induction or microwave transmission without wires. The document outlines Nikola Tesla's early experiments with WPT in the late 1800s and discusses modern implementations like transferring power to electric vehicles or using solar power satellites to beam energy from space. While WPT could address energy losses during transmission and power remote areas, high initial costs remain a challenge to widespread adoption.
Disclosed is an optical fiber comprising a center core which forms a passageway for transmitting
optical signals and has a refractive index N1, and a cladding which encloses the center core and
has a refractive index N0. The optical fiber further comprises an upper core, which has a
distribution of refractive indices increased starting from a refractive index N2 (>N0) at its outer
circumference to the refractive index N1 at its internal circumference, and a minutely depressed
refractive index region, which is interposed between said upper core and cladding and has a
refractive index N3. The refractive index N3 is lower than the refractive index N0.
The document summarizes a seminar on wireless electricity transmission using microwaves. It discusses how Nikola Tesla experimented with wireless power in the late 19th/early 20th century. More recently, researchers have demonstrated converting microwaves to electricity using rectennas with over 95% efficiency. For wireless power transmission, microwaves would be beamed to rectennas on Earth from satellites in low or geostationary orbit. While promising, challenges include the large size needed for rectennas and high costs of over $70 billion to implement.
Graded index (GRIN) optical fibers have a refractive index that decreases continuously from the core center to the cladding. This results in curved ray paths inside the core rather than straight lines, reducing intermodal dispersion. The optimal refractive index profile for minimizing dispersion is parabolic. Attenuation in optical fibers is due to various factors including material absorption, scattering, and bending losses. Rayleigh scattering increases at shorter wavelengths, while absorption peaks exist for hydroxyl and metal impurities.
Rural electrification has played an important role in India's economic development but progress has fallen short of targets. Over the decades since independence in 1947, millions of villages have gained access to electricity, with the number of electrified villages growing from 1,500 in 1947 to over 493,000 by 2009. However, targets set in various five-year plans to accelerate rural electrification were often missed. More recently, programs like the Rajiv Gandhi Grameen Vidyutikaran Yojana aimed to fully electrify India's estimated 600,000 villages and provide electricity access to all rural households by 2012, but this goal was not achieved either. Continued efforts are needed to close the remaining gap and fulfill the
Light emitting diodes (LEDs) emit light when electrons recombine with holes, releasing photons. LEDs have three layers: p-type and n-type semiconductors separated by a depletion region. When forward biased, electrons from the n-layer and holes from the p-layer recombine in the depletion region, emitting photons. Unlike silicon diodes that emit mostly heat, LEDs use materials like gallium arsenide that emit higher energy visible light photons due to a larger bandgap between conduction and valence bands.
This document discusses wireless power transmission (WPT) and compares microwave and laser transmission methods. It describes how a rectenna works to receive microwaves with 85% efficiency within 5km. Solar power satellites that transmit power via microwaves from space are also discussed, including their advantages over earth-based solar like constant sunlight. Current development of a low-cost Japanese demonstration project by 2025 and potential applications of WPT like electric vehicles are mentioned.

WiTricity - Electricity through Wireless TransmissionAmber Bhaumik
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.

1. A multistage amplifier achieves greater voltage and power gain by using multiple amplification stages connected in cascade. The overall voltage gain is equal to the product of the individual stage gains.
2. Gain is often expressed in decibels (dB) which allows both small and large quantities to be conveniently represented on a logarithmic scale corresponding to human perception. The overall multistage amplifier gain in dB is the sum of the individual stage gains in dB.
3. Common types of coupling between stages include RC coupling using capacitors, direct coupling without coupling elements, and transformer coupling. RC coupling is inexpensive but limits low frequency response while direct coupling can amplify low frequencies without coupling elements.

Felix Langley, Network Technical Head at Network Rail, gave an insight into the diverse array of power engineering on the UK Railway, including AC/DC electrification, SCADA systems and the non-traction power supplies that feed signalling systems, points heating and level crossings.
HVDC transmission systems were developed as an alternative to AC transmission for long distance or underwater power transmission. HVDC uses voltage source converters to convert AC to DC for transmission and back to AC at the receiving end. Some key advantages of HVDC include being able to transmit power over longer distances than AC systems and enabling asynchronous connections between separate AC networks. The first commercial HVDC system was installed in 1954 between Sweden and Gotland island. Important applications of HVDC systems include bulk power transmission over long distances, underwater cables longer than 30 km, and asynchronous links between AC systems.
HVDC transmission systems use direct current for the transmission of electrical power over long distances or undersea. They have advantages over AC transmission such as lower transmission losses over long distances and the ability to interconnect unsynchronized AC power systems. HVDC technology has evolved from early electromechanical systems using motor-generator sets to modern thyristor-based systems. HVDC is used for long distance bulk power transmission projects in India such as Rihand-Delhi and Chandrapur-Padghe.
