摘要

PROBLEM TO BE SOLVED: To provide a photonic crystal slab electromagnetic wave absorber of a thin flat surface type, easy to be processed, having high capturing and absorbing effect, a high frequency metal wiring circuit to which the photonic crystal slab electromagnetic wave absorber is applied, an electronic component, a transmitter, a receiver, and a proximity radio communication system.SOLUTION: A photonic crystal slab electromagnetic wave absorber 1 includes: a two-dimensional photonic crystal slab 12 composed of a semiconductor material; and lattice points 12A for forming a resonance state that are periodically disposed in the two-dimensional photonic crystal slab and are capable of capturing an electromagnetic wave incident from an outside by resonating an electromagnetic wave at a band end of a photonic band structure of the two-dimensional photonic crystal slab within a plane of the two-dimensional photonic crystal slab. The two-dimensional photonic crystal slab is doped with impurities and is capable of absorbing the captured electromagnetic wave at a resonance frequency of the band end of the two-dimensional photonic crystal slab.
