In-band full-duplex (IBFD) technology can enable unique system capabilities and network
architectures by allowing devices to transmit and receive on the same frequency at the same …

Increased demand for higher spectrum efficiency, especially in the space-limited chip, base
station, and vehicle environments, has spawned the development of full-duplex …

Lorentz reciprocity is a fundamental characteristic of the vast majority of electronic and
photonic structures. However, non-reciprocal components such as isolators, circulators and …

Recently, we demonstrated the first CMOS nonmagnetic nonreciprocal passive circulator
based on N-path filters that uses time variance to break reciprocity. Here, the analysis of …

Full duplex wireless has drawn significant interest in the recent past due to the potential for
doubling network capacity in the physical layer and offering numerous other benefits at …

In this paper, we discuss the design rationale and guidelines to build magnet-less circulators
based on spatiotemporal modulation of resonant junctions consisting of first-order bandstop …

Wireless backhaul has recently gained a significant amount of interest as a cost-effective
solution in comparison with conventional backhaul technologies with dedicated microwave …

Linear, time-invariant, passive circuits and systems constructed from conventional materials
with symmetric permittivity and permeability tensors are reciprocal. Breaking Lorentz …

This paper proposes an active radio frequency (RF) cancellation solution to suppress the
transmitter (TX) passband leakage signal in radio transceivers supporting simultaneous …

This paper presents an iterative estimation and cancellation technique for nonlinear in-band
full-duplex transceivers with IQ imbalances and amplifier nonlinearities. The estimation …
