Claim Text:
1. A method for attenuating the communication signals transmitted from a mobile device's antenna in the proximity of the mobile device's ear piece, the method comprising: determining the position of the antenna; determining the position of the ear piece relative to the antenna; determining a phase shift required to create destructive interference with the communication signal at a position proximate the ear piece; positioning a reflector such that the propagation of the communication signal to the reflector and the propagation of a reflected communication signal from the reflector to the position proximate the ear piece results in the phase difference between the communication signal and the reflected communication signal at the position proximate the ear piece: wherein the reflector is attached to the mobile device; wherein the phase difference is (2n−1)λ/2, where n is an integer.
