A Compact Microwave Rectifier for Wireless Power Transfer and Energy Harvesting Applications

2024 18th European Conference on Antennas and Propagation (EuCAP)
This paper presents a microwave rectifier with compact size and high efficiency for radio frequency (RF) energy harvesting and low-power internet of things (IoT) applications. The proposed rectifier consists of a matching network, a doubler rectifier, a lowpass (LPF) structure and a low-power electronic circuit.

A Mystery of the Inconsistency Between Microwave Polarimetric Observations and Radiative Transfer Simulations

Geophysical Research Letters
A factor of 2 difference is found between microwave brightness temperature (TB) observations and simulations from vector radiative transfer models. A physical explanation of this difference is related to the calibration process.
