SPURIOUS RADIATION SUPPRESSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve a problem associated with techniques to block off an electromagnetic radiation source using metal or electromagnetic wave absorbing material, that spurious radiation is suppressed but diffusion of heat is blocked. SOLUTION: The spurious radiation suppression system is for an electromagnetic radiation source which radiates electromagnetic waves and is provided with an aerial circuit using a conductor ring placed in proximity to the radiation source so that the radiation source is encircled with the conductor ring. The system converts the energy of electromagnetic waves absorbed by the conductor ring into thermal energy by a parasitic impedance based on the conductor ring or an impedance connected with the feed point of a loop antenna formed by the conductor ring, and diffuses the thermal energy in the free space.
