EFFECT OF SEGMENTATION OF CONDUCTIVE COATINGS ON THE RADIO-WAVE TRANSMISSION THROUGH SOLAR CONTROL SHEET GLASS

It is a well known phenomenon that the amplitude of radio waves propag ating through solar control glass is greatly reduced, because the elec trical conductive film on the surface of solar control glass reflects the incident radio waves with frequencies lower than that of the plasm a oscillation of free electrons in the conductive film. As a result of the moment method analysis of the scattering problem in the spectral domain, it was found that the amplitude of radio waves was not damped when the conductive film was divided into discontinuous segments with a periodic array because the motion of free electrons induced by the m agnetic field of incident radio waves is restricted in the divided fil m. The effect of dividing the conductive film of solar control glass h as been examined experimentally in the television wave region.
