In general, reciprocity requires that signals travel in the same manner in both forward and
reverse directions. It governs the behaviour of the majority of electronic circuits and …

In order to adapt to the upgrading of wireless communication system, thin film bulk acoustic
resonator (FBAR) has become one of the research hotspots in the communication field. The …

In this article, a new generation of magnet-free circulators with high performance is
proposed. Circulators are crucial devices in modern communication systems due to their …

This paper reports the first demonstration of a magnet-free, high performance
microelectromechanical system (MEMS) based circulator. An innovative circuit based on the …

In wearable or implantable biomedical devices that typically rely on battery power for
diagnostics or operation, the development of flexible piezoelectric nanogenerators (NGs) …

Suitably tailored forms of spatiotemporal modulation in electronic circuit networks have been
recently employed to overcome fundamental challenges in modern electronic systems …

This exciting new book examines the feasibility of using a method of doubling the capacity of
cellular networks by simultaneously transmitting and receiving signals at the same …

In this brief, the method of using nonreciprocal circulator networks to construct
multifunctional components is proposed. A nonreciprocal single-ended bandpass filter …

This paper reports for the first time a magnetless microstrip circulator with a filtering
response. By coupling static resonators to spatio-temporally modulated resonators, two …

In this study, we explore the design, simulation, and implementation of a magnetic-free radio
frequency (RF) circulator using spatiotemporal modulated thin film surface acoustic wave …
