Abstract:
1. An electromagnetic absorption panel for absorbing electromagnetic waves of a wireless local area network, wherein: first and second transparent glass sheets are arranged at an interval by having a spacer at a circumferential end portion thereof so that a hollow layer sealed between the first and second glass sheets is formed; each of the first and second glass sheets has a thickness in a range from 2.5 to 20 mm, and the hollow layer has a thickness in a range from 2.5 to 15 mm; at least one glass sheet of the first and second glass sheets is formed with a resistive film on a surface thereof on a side facing the hollow layer, said resistive film having a surface resistance in a range from 20Ω/□ to 2 kΩ/□; and the resistive film is prepared by forming in the following order a dielectric film, a metal film, and a further dielectric film on the at least one glass sheet.
