Influence of extraneous objects; the success of the proposed resonance based wireless energy transfer scheme depends strongly on the concentration of the objects resonances, therefore their sensitivity to the near presence of random non resonant extraneous objects is another aspect of the proposed scheme. The appropriate analytical model now is the perturbation theory( PT), which suggest that in the presence of an extraneous object the field amplitude inside the resonant object 1 satisfies it. However the significant lost can be detrimental to the functionality of the energy transfer system because it cannot be replaced.
An extremely important implication relates to safety considerations for human beings. Humans are also non-‐ magnetic and can sustain strong magnetic fields without undergoing any risk. This goes for the second example of capacitively-‐ loaded conducting wire loops where its operation in the air is magnetic, since almost every-‐ day materials are non-‐ magnetic, they respond to magnetic fields in the same way as free space, this way it will not disturb the resonance of a conducting wire loop. The only perturbation that is expected to affect these resonances is a close proximity of large metallic structures.
An example of where magnetic fields are safely used on humans is the magnetic resonance imaging( MRI) technique for medical testing since a strong electric near field is also not present and the radiation produces from this non-‐ radioative scheme is minimal, it is expected that the roposed energy-‐ transfer method should be safe for living organism.
Having the two classes of resonant system studied, the immunity to extraneous objects and the absence of risks for humans makes the conducting wire loops the most suitable choice for real-‐ world applications, on the other hand, systems of disks of high refraction, have the advantage to be applicable in smaller length scales.
Efficiency of energy-‐ transfer scheme; it is based on the combination of a resonant source and device in the presence of a set of extraneous objects. This ocurrs when energy is being drained from the device at rate for use into operational work. Different temporal systems can be used to get power from the device, which will help obtain dependence on the combined systems.
As a conclusion, we present a system based on“ strongly-‐ coupled” resonances for mid-‐ range wireless non radiative energy transfer. It was also considered that all results can be applied for dynamic geometries of mobile objects, since the energy transfer time is shorter than any timescale of macroscopic objects.
The analyses of simple implementations of geometrics provide encouraging performances and an improvement in the design optimization. In the microscopic world, where there are smaller wavelengths and smaller powers are needed, one could use it to implement optical inter connects for cmos electronics, or to transfer energy to Nano-‐ objects without worrying about the alignment between the sources and devices. Also the range of applicability could be extended to acoustic systems, where the source and device are connected through a condensed object.
