Title:
METAL PLATE LENS AND PERFORMANCE EVALUATION METHOD OF RADIO WAVE ABSORBER USING THE SAME
Document Type and Number:
Japanese Patent JP2014165808
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compact performance evaluation device which accurately performs performance evaluation of a radio wave absorber using a metal plate lens and is easily manufactured.SOLUTION: A metal plate lens is characterized in that, in a state where a plurality of metal plates 1 are arranged in parallel with an electric field direction A by keeping an equivalent space d between the respective metal plates 1, one end surface 1a of each of the plurality of metal plates 1 is located on the same half-recessed spherical surface 2, and the other end surface 1b thereof is located on the orthogonal surface 3 having the same direction as the electric field direction A. When dielectric bodies are interposed in the respective spaces d, the dielectric bodies cooperate with each other, and are fitted to the half-recessed spherical surface 2 on each one end surface, then made to be fitted to the orthogonal surface 3 on each other end surface.
