Energy Recovery From Microstrip Passive Circuits
IEEE Access, 2016 In this paper, the energy recovery in microstrip passive circuits from the power losses into heat is studied. For this purpose, a thermoelectric generator (TEG) based on the Seebeck effect principle is used, which converts part of the power dissipated ...
