By opening and closing the switches, the transmissivity of the surface may be adjusted over a broad range of frequencies. In particular, the surface may be placed into open and closed states, creating an electronically- controllable shutter. The ability of the shutter to act as an open or a closed surface over a broad range of frequencies, incidence angles, and polarization states is investigated using simulations and measurements, and the feasibility of the system is thereby demonstrated. © 2010 IEEE.Electromagnetic scattering; frequency selective surfaces (FSSs); genetic algorithms (GAs); slot antennas; tunable filtersClosed surfaces; Electromagnetic scattering; frequency selective surfaces (FSSs); Incidence angles; Metallic surface; Polarization state; Selftuning; Simulations and measurements; Transmissivity; Tunable filters; Antenna arrays; Electromagnetic wave scattering; Electromagnetism; Genetic algorithms; Tuning; Slot antennasjournal article10.1109/TAP.2010.20964012-s2.0-79551640538
