Thanks, RICC for recognizing me again third time. I hope this time RICC has something very special for awardees , at least a trip to the university or something like that… or some funding opportunity…

 A New Innovative Optical Approach for Long-Range RF Transmission Systems to Minimize the Aperture Area of Receiver

Abstract

In Wire-less Power Transmission (WPT) reducing the aperture size of receiving station, increasing the concentration ratios and decreasing the effect of side-lobe levels much of the concern has been related with Antenna pattern Optimization problems. Here, in this paper we have introduced a novel optical approach that could be used to curb these problems. In our approach, the generated radiated Radio Frequency beam is made to travel through a unique and specially designed Ultra-large Fresnel Array (UFA) that focuses the radiated RF beam from the RF transmitter
to the receiver/Rectenna. The aperture size of the receiver/Rectenna remains the function of Focal length (f) & aperture size (AT) of the UFA, and the distance (L) between UFA and Rectenna. In general, the basic design considerations of the UFA and its cost-effective impact to the space-based power systems in future is described here. The case of 1979 Reference concept from NASA/DOE studies is also used here to demonstrate how the aperture size of receiving station would get reduced with the help of this UFA. The approach has the potential to be used in areas of space applications including SSPS and earth observation radiometry.
