1. Rationale of the study
Our new technology the energy transfer wherein energy can be transferred from a source to a load via coupled magnetic resonance in the non radiative near field that can be used in some equipment that used in some electric energy as a source like the electric vehicles (EVs). We can use this energy transfer as a charger to EVs by microwave beams and laser beams to realize the remote energy supply using directional antenna. However when there is a obstruction in the path the transmission of power may dissipate , and also is dangerous to human bodies and other organisms.

So the basic theory of this technology is that two separate coils with some resonance frequency possible to form a resonance system based on high frequency magnetic coupling and exchange in a high efficiency, while the coupling effect is weak between those objects with different resonance frequency. This technique can be used to provide energy for electricity equipment wirelessly in a certain distance.

2. Hypothesis tested
Having a wireless energy transfer is often hard to believe. So they make an hypothesis test for the wireless that transfer energy using resonance. Resonance is created by the sound that come in vibrating things. Since resonance phenomenon existed everywhere and it has energy, they use this to s

So the experiment was conducted using two fork. Hitting one of the fork to make it phonating, then they hold it to stop phonating. So, they concluded that the other fork produce phonating sound without touching it or andy disturbance on the fork.

3.0 Materials and Methods of Application Systems
The inventors use the microwave beams and laser beams to realize the remote energy supply using the directional antenna, they use this method to transfer energy, any obstruction in the transfer path that is not allowed and it is dangerous for human bodies or other organisms which in the energy transfer path. The basic principle of this technology is that two separate coils with the same resonance frequency are possible to form a resonant system based on high frequency magnetic coupling and exchange energy in a high efficiency, while the coupling effect is weak between those objects with different frequency the medium of nergy transfer is an alternating magnetic field.

3.1 Experiment Arrangement
The control methodology on this study was based on the energy transfer experiment. It conducted two experiment with different materials and distance to see the difference. In the first experiment the materials used are inductance coil with a diameter of 160mm, diameter of conductor section is 1.2mm, coil turns is 4, capacitor 6.6 mf with withstand 30v, power is an 110 V DC, and its maximum output current is 3A. The result shows that the power can be transferred is up to 500 w, the transfer efficiency is more than 60% and maximum distance of energy transfer can reach 300mm. The another energy transfer experiment they use a higher value of the materials used, 2 turns coils and 25 v dc power which is lower to the first experiment the result is just the same but the transfer distance they use is 1 ,meter which is longer to the first one. In this experiment of energy transfer shows that transfer efficiency varies with the distance between the source and receiving resonance coils. The longer the distance between the source and receiving resonance coils the lower the transfer power and efficiency 3.2 Fault Detection System

The radiating electromagnetic wave itself contains energy, no matter whether there is a receiver or not, the energy of electromagnetic wave is continuously consumed. Classifying the fault operation into different types is also required. In order to obtain data sets for each kind of faults, one has to impose those faults and take the corresponding measurement of the microenvironment variables.

The energy supply of source is provided by power convert module, inductor L and capacitor C constitute a...
