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 ...

When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give ...

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 ...
