A simple model allowing us to predict beam steering characteristics in a Fabry–Perot (FP) cavity antenna is presented in this letter. The structure consists of a ground plane and a phase-modulated metasurface used as a partially reflective surface (PRS). The aim of this letter is to present a simple model that allows calculating the necessary phase modulation for a desired beam-steering angle. Furthermore,...
In this paper, we present an affordable interferometer with its dedicated electronics system. The interferometer uses an infrared source and is based on a telecom waveguide technology. The electronics part has been fully developed in our laboratory with available commercial components. Experimental results are provided and compared to those obtained with a computer and commercial acquisition boards.
