Abstract
Disclosed is an intelligent reflecting surface including a plurality of radio-wave reflecting devices, an adjusting substrate over the plurality of radio-wave reflecting devices, and an anti-reflective film located over the adjusting substrate and configured to absorb radio waves. Each of the plurality of radio-wave reflecting devices includes a pair of substrates and a plurality of radio-wave reflecting elements between the pair of substrates. The anti-reflective film has a lattice shape as a whole. An edge is covered by the anti-reflective film and a portion surrounded by the edge is exposed from the anti-reflective film in each of the plurality of radio-wave reflecting devices. A frequency of the radio waves is equal to or greater than 400 MHz and equal to or less than 50 GHz, for example.
