Abstract: We propose a two-dimensional (2D) resonant-tunneling-diode (RTD) oscillator array to generate quasi-plane terahertz (THz) waves. Dual-RTD slot antennas are employed to form the 2D array ...

Abstract: This paper presents a reconfigurable intelligent surface (RIS) to control the direction of the reflected wave independently in each orthogonally dual-polarized incident wave for deploying ...
