Abstract
A wire grid is assumed to be composed of parallel infinitely long thin perfectly conducting or conducting wires. Effects of random positioning errors upon grid impedance, reflection and transmission characteristics are analyzed theoretically for such a grid. It is studied that increasing random errors in positioning of wires increases the magnitude of wire grid impedance. Also, it reduces reflection from a wire grid. This reduction is more dominant at normal incidence. Likewise, increasing error in positioning of wires increases transmission through a wire grid.
