recommendations! Published in 2025 at "International Journal of Microwave and Wireless Technologies"

DOI: 10.1017/s175907872510233x

Abstract: This paper presents the first reported design of a balanced nonreciprocal bandpass filter with both common-mode (CM) and differential-mode (DM) reflectionless characteristics. The nonreciprocal behavior is achieved using a time-modulated resonator, which isolates in-band backward… read more here.

DOI: 10.1109/tia.2024.3413037

Abstract: One of the significant disadvantages of high frequency power electronics converter is its Electromagnetic Compatibility(EMC). The converters must meet different Electromagnetic interference(EMI) standards, i.e., CISPR, and IEC set by various international bodies for commercialization. Low… read more here.
