New energy harvesting technologies have drawn interest in recent years for both military
and commercial applications. We present complete analysis of a novel device technology
based on nanowire antennas and very high speed rectifiers (collectively called
nanorectenna) to convert infrared and THz electromagnetic radiation into DC power. A
nanowire antenna can receive electromagnetic waves and an integrated rectifier can
convert them into electrical energy. The induced voltage and current distributions of
nanowire antennas for different geometric parameters at various frequencies are
investigated and analyzed. Also, nanowire antenna arrays with different geometries and
distributions are examined. Moreover, novel nanoantennas are proposed for broadband
operation and power conversion. All numerical computations are conducted using Ansoft
HFSS. An incident plane wave was used to excite each device and simulations were carried out
for frequencies between 0 and 200 THz. A voltage is induced in each device and it is
measured in the thin oxide layer. Finally, optimum geometries of nanowires are proposed
in order to maximize the amount of infrared power that is harvested.
