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 ...

Before the US-Israeli strikes on Iran, Washington assembled its largest force and some of its most powerful weaponry in the Middle East in decades. President Donald Trump had warned the US was “locked ...
