Millimeter-wave propagation at street level in an urban environment // IEEE Transactions on Geoscience and Remote Sensing 26 (3). IEEE, May 1988. DOI:10.1109/36.3038. с. 368–380.

When the LOS followed a path directly through clear glass walls, the attenuation was small at all probe frequencies. However, when the glass wall had a metalized coating to reduce ultraviolet and infrared radiation, the attenuation increased by 25 to 50 dB for each metallized layer. In most cases no signals could be detected through steel reinforced concrete or brick buildings."
