  • Abstract
    A method of treating reflective surfaces to reduce reflections causing signal drop-outs or antenna side lobes is described. The surface is constructed of small cells that reflect such that the relative phase of individual reflections is randomized and does not sum constructively or destructively. Tests of return loss and oblique reflection with comparisons to flat plates and RF absorber show performance similar to that of RF absorber.
