In this letter, a frequency-tunable rectifier in the $C$ -band designed by a hybrid semiconductor integrated circuit (HySIC) concept is proposed. A GaAs monolithic microwave integrated circuit (MMIC) and a Si radio frequency integrated circuit (RFIC)

We succeeded in extending the decay time of terahertz electromagnetic waves from coherent longitudinal optical (LO) phonons in GaAs epitaxial layers with the use of fast atom bombardment, a treatment method for introducing defects and/or disorders at

We report on the irreversible and reversible resistance changes for γ-ray irradiation in amorphous GeTe thin films with Ag electrodes. The γ-ray irradiation at a dose of 1 kGy irreversibly decreased the DC resistance by two orders of magnitude. The

For the first time, we propose a combination of coupled defected ground structure (DGS) resonators for wireless power transfer and coupled Figure-8 inductors for information transfer. This combination allows the realization of a simultaneous compact
