Abstract: To generate high-power, high-directivity terahertz (THz) radiation, in this article, we propose and fabricate a 2-D resonant-tunneling-diode (RTD) THz oscillator array. The array is formed ...

Abstract: Broadband beamformers designed as two-dimensional (2-D) spatially-interpolated finite-extent impulse responses (FIR) filters, using a cascade structure, cannot employ sparse linear arrays ...
