DOI: 10.1103/physreve.105.054211

Abstract: We propose a coupled phase oscillator model with inertia and study the vortex motion in the model when the external force is applied at the boundaries. The vortex exhibits a glide motion when the external… read more here.

DOI: 10.1103/physreve.110.024219

Abstract: Synchronization behaviors in globally coupled phase oscillators with symmetric bimodal frequency distribution and periodic coupling are studied. It is found that by a proper setting of the frequency of the periodic coupling, the synchronization propensity… read more here.

DOI: 10.1109/jsac.2022.3192053

Abstract: A simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) assisted multi-user downlink multiple-input single-output (MISO) communication system is investigated. In contrast to the existing ideal STAR-RIS model assuming an independent transmission and reflection phase-shift control,… read more here.

DOI: 10.1109/lcomm.2024.3462798

Abstract: A simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided multiple-input multiple-output (MIMO) secure communication system is explored. A practical coupled phase-shift model of STAR-RIS is taken into account for beamforming design. Based on this… read more here.

DOI: 10.1109/lwc.2022.3219020

Abstract: A general optimization framework is proposed for simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) with coupled phase shifts, which converges to the Karush–Kuhn–Tucker (KKT) optimal solution under some mild conditions. More particularly, the amplitude… read more here.
