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.
