$\mathrm{A}2.6 \mathrm{V}-10\ \mu \mathrm{A}$ Nanorectenna Harvester based on thermal radiation of the car exhaust system

In this paper, for the first time, the design and simulation of a thermal nanorectenna energy harvester for harvesting the electromagnetic energy from the car exhaust system is presented. The nanorectenna system is composed of three gold arrow-bowtie nanoantennas with different resonance frequencies and a geometric nanodiode in the feed gap of each nanoantenna. The resonance frequencies at about 50 THz, 65 THz, and 83 THz correspond to the frequencies of the thermal radiation emitted from the exhaust tailpipe, catalytic converter, and manifold, respectively. The proposed
