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.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

9. TESLA COIL
• Inventor Nikola Tesla invented Tesla Coil in 1891.
• It works on the principle of Electromagnetic Induction.
• Wardenclyffe Tower was a huge tower made by tesla.
• This tower was actually a huge tesla coil.
• Through which Tesla could transmit Wireless Electricity.
10. INDUCTIVE COUPLING
• In Inductive Coupling (electromagnetic induction
or inductive power transfer, IPT), power is
transferred between coils of wire by a magnetic
field.
• It induces an alternating EMF (voltage) by
Faraday's law of induction, which creates an AC
current in the receiver.
• The fastest growing use is wireless charging pads
to recharge mobile and handheld wireless devices
such as laptop and tablet computers.
11. RESONANT INDUCTIVE COUPLING
• Resonant inductive coupling is a form of inductive coupling in
which power is transferred by magnetic fields (B) between two
resonant circuits (tuned circuits).
• Resonant circuits interact with each other with so much
intensity that stray magnetic fields doesn’t do any severe
effect in transmission.
• This technology can be used to power every electronic
item in our room e.g. fan , table lamp , T.V.
12. CAPACITOR COUPLING
• In capacitive coupling (electrostatic induction), energy
is transmitted by electric fields between electrodes
such as metal plates. The transmitter and receiver
electrodes form a capacitor, with the intervening
space as the dielectric.
• Capacitive coupling has only been used practically in
a few low power applications, because the very high
voltages on the electrodes required to transmit
significant power can cause unpleasant side effects
such as noxious ozone production
13. MAGNETO DYNAMIC COUPLING
• In this method, power is transmitted between two rotating
armatures, one in the transmitter and one in the receiver,
which rotate synchronously, coupled together by a magnetic
field generated by permanent magnets on the armatures.
• This device has been proposed as an alternative to
inductive power transfer for noncontact charging of electric
vehicles.
• Google is now using this wireless E.V charging technique
to charge their electric vehicles.
14. MICROWAVE
S• Power transmission via radio waves can be made
more directional, allowing longer distance power
beaming, with electromagnetic radiation, typically in
the microwave range.
• In World War II, the idea of using microwaves to
transfer power was researched and was used to
propelled miniature helicopter by microwave power.
• Power beaming using microwaves has been
proposed for the transmission of energy from
orbiting solar power satellites to Earth and the
beaming of power to spacecraft.
15. LIGHT WAVES
• In the case of electromagnetic radiation closer to the
visible region of the spectrum , power can be
transmitted by converting electricity into a laser
beam that is then pointed at a photovoltaic cell.
• Laser 'power beaming' technology was explored in
military weapons and aerospace applications. Also,
it is applied for powering of various kinds of sensors
in industrial environment.
17. ADVANTAGES
• Wireless Power Transmission system would
completely eliminates the existing high-tension power
transmission line cables, towers and sub-stations.
• Loss of transmission is negligible in the Wireless
Power Transmission. Therefore, the efficiency of this
method is much higher than the wired transmission.
• The power failure due to short circuit and fault on
cables would never exist in the transmission.
18. DISADVANTAGES
• The Capital Cost for practical implementation of WPT
seems to be very high.
• Long distance charging ,High current and voltage
charging are not supported & very fast charging is not
possible.
• The interference is seen in microwave wireless
transmission with present communication systems.
