On the Potential Energy Output of a System Transporting the Electromagnetic Energy by Means of Microwave Beams

摘要

It is proposed to use such distribution of the radiated field in a wireless energy transportation system that is similar to the distribution of the modified TEM_(10) mode generated by a laser. It is shown that, in this case, the product of the aperture efficiencies of radiating and receiving apertures substantially exceeds the value of this parameter corresponding to the uniform and optimum Gaussian field distributions. It is found that, in this case, the potential energy output of the energy transportation system increases approximately by a factor of three and can reach about 15 GW at a wavelength of 5 cm for the antenna and rectenna diameters of 1.0 km and 7.4 km, respectively.
