Abstract

A method for reducing the harmful effect of radiation emitted by RF and EMF radiation emitting devices such as mobile phones on living organisms, characterised by altering the waveform shape of said radiation in such a way that the desired function of the device is not changed or affected and that harmonics in the region of 50Hz -75GHz which could cause the harmful effect are minimised. This is achieved by using a passive matrix assembly or an active system to modify the emitted waveform shape by: 1. minimising the presence of sharp peaks i.e. the waveform is softened; 2. increasing the wavelength, decreasing the frequency and decreasing the amplitude of any transients present. As a consequence of these changes harmonics generated by the waveform are minimised.
