In this article, we provide a comprehensive review of past and present efforts in the field of
microwave nonreciprocity with an emphasis on the most commonly used nonreciprocal …

The relentless demand for data in our society has driven the continuous evolution of
wireless technologies to enhance network capacity. While current deployments of 5G have …

This tutorial provides an intuitive and concrete description of the phenomena of
electromagnetic nonreciprocity that will be useful for readers with engineering or physics …

In this paper, we demonstrate, for the first time, an isolating bandpass filter with low-loss
forward transmission and high reverse isolation by modulating its constituent resonators. To …

This brief presents a novel frequency reconfigurable microstrip non-reciprocal bandpass
filter based on time-modulated microstrip resonators. The modulation is achieved by loading …

In this paper, we introduce the first integrated circuit (IC) implementation of spatiotemporally
modulated angularmomentum (STM-AM)-biased magnetless circulators. The design is …

Reciprocity is a fundamental physical principle that roots in the time‐reversal symmetry of
physical laws. It allows making predictions on any arbitrary complex system's response and …

Recently, CMOS non-magnetic circulators have been demonstrated based on switch-based
spatio-temporal conductivity modulation, but these initial demonstrations remain limited in …

This letter presents a magnet-less nonreciprocal bandpass filter (BPF) that uses coupled
static and time-modulated resonators. This coupling allows the nonreciprocal BPF to …

In this article, we present a frequency tunable magnetless nonreciprocal bandpass filter
(BPF) that uses time-modulated quarter-wave microstrip line resonators. The proposed …
