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 ...

Houseplants are one of the best ways to style a home. Not only do they instantly lift the look of a room, but they also bring a sense of calm, peace, and serenity to the living space. They come in ...

Abstract: A new two-dimensional spatial spectral estimation direction finding method based on L-shaped array and time modulation theory is proposed. The main principle of this method is to generate a ...
