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 developed a photonically actuated ultrawideband, two-dimensional transmit array using a Fourier optical lens as a beamformer. Data encoding was developed, in which custom IF ...
