Title: Innovations of George V Eleftheriades

Introduction

George V Eleftheriades is a notable inventor based in Scarborough, Canada. He holds a total of 6 patents that showcase his contributions to the field of electromagnetic wave manipulation and phased array technology. His work has significant implications for various applications in telecommunications and radar systems.

Latest Patents

One of his latest inventions is the "Nonreciprocal beam steerable metasurfaces." This invention presents a full-duplex nonreciprocal-beam-steering transmissive phase-gradient metasurface. The metasurface comprises a conductor layer interposed between two dielectric layers. Each of the dielectric layers contains a plurality of meta-atoms embedded within. Each meta-atom consists of phase shifters and antenna elements. The metasurface functions such that when an electromagnetic wave is received at its surface, it transmits a wave with the same frequency but in a different direction in space.

Another significant invention is the "Peripherally excited phased arrays." This invention introduces a new phased array, known as the peripherally-excited phased array (PEX-PA). The PEX-PA consists of an electrically large metallic cavity excited by weighted antenna sources only at its periphery. The top surface of the cavity is patterned with a suitable configuration of apertures, while the cavity is filled with a dielectric material. The PEX-PA is capable of beam scanning, allowing for one or multiple beams over a wide range of directions in air, with a drastically reduced number of passive or active phase shifters.
