A novel design of a digital step attenuator in waveguide technology is presented. The attenuator design is based on a novel unit cell that consists of a quarter-wave resonator (QWR), modified with an RF memristor and an RF resistor. The resonators ar

This paper gives an overview of a method for spacetime synthesis of pulsed beams with arrays of isotropic radiators. The proposed method is based on discrete Radon transform and its inverse, solving for optimal source pulses that enable a given radia

A method for beam synthesis with arbitrarily configured transmitting pulsed antenna arrays based on the discrete Radon transform and its inverse is investigated. Remaining in the digital domain, by numerical means an optimal set of wave forms corresp
