Integrated sensing and communication (ISAC) is a promising technology to fully utilize the precious spectrum hardware in wireless systems, which has attracted significant attentions recently. This paper studies ISAC for important challenging monostatic setup, where one single node wishes simultaneously sense radar target while communicating with receiver. Different from most existing schemes th...

We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...

Multiplexers and power combiners/dividers are crucial in many applications of electromagnetic waves including microwave terahertz communication. Full-duplex communication requires the separation transmitted received signals; thus, non-reciprocal multiplexers very essential. In this work, we present numerically study a design concept for such circuits from topological cavities. First, quad-port ...

The challenge to in-band full-duplex wireless communication is managing self-interference. Many designs have employed spatial isolation mechanisms, such as shielding or multi-antenna beamforming, to isolate the self-interference wave from the receiver. Such spatial isolation methods are effective, but by confining the transmit and receive signals to a subset of the available space, the full spa...
