Energy scavenging from the diurnal cycle with a temperature-doubler circuit and a self-adaptive photonic design [PDF]
NanophotonicsA temperature-doubler circuit is the functional equivalent of a voltage-doubler in the thermal domain. Effective temperature-doubler circuits could benefit energy scavenging from fluctuating thermal resources, e.g. the diurnal cycle. However, the current

A 135-190 GHz Broadband Self-Biased Frequency Doubler using Four-Anode Schottky Diodes
Micromachines, 2019 This paper describes the design and demonstration of a 135−190 GHz self-biased broadband frequency doubler based on planar Schottky diodes. Unlike traditional bias schemes, the diodes are biased in resistive mode by a self-bias resistor; thus, no ...

IEEE transactions on industrial electronics (1982. Print), 2023 In dynamic wireless power transfer (DWPT) systems, the power oscillation phenomena caused by coupling fluctuation are always hard to avoid. Moreover, if the adjacent track coils are excited by different inverters without synchronized drive signals, there
