▎ 摘　　要

NOVELTY - The chamber has a first surface (1) provided with an ideal electrical conductor characteristic parallel to a second surface (2). A third surface (3) is provided with an ideal magnetic conductor characteristic parallel to front and back. A fourth surface (4) and a fifth surface (5) are provided with high transmission performance for electromagnetic wave parallel to left and right. A sixth surface (6) is provided with high absorption characteristic opposite to the fifth surface and high absorption rate. An electromagnetic wave absorbing body adjusts an absorption frequency by designing a structure of an array unit. Two-dimensional periodic array unit utilizes a patterned graphene structure to construct the array unit by an external voltage for realizing a dynamic tuning of the wave-absorbing frequency. USE - Low electromagnetic disturbance atomic gas chamber for electromagnetic metamaterials. ADVANTAGE - The chamber can effectively destroy a Fabry Perot cavity resonance condition formed by the parallel glass surface in a microwave electric field so as to reduce deviation between an atomic gas chamber internal electric field and a real electric field, thus improving measuring accuracy of the microwave. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a low electromagnetic disturbance atom gas chamber composed of an electromagnetic metamaterial. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a low electromagnetic disturbance atomic gas chamber. Surfaces (1,2,3,4,5)
