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: Aiming at the typical environment of underwater target passive positioning, the performance of a two-dimensional DOA estimation method based on L-shaped array is simulated. Firstly, the ...
