The invention provides a low-electromagnetic disturbance atomic gas chamber made of an electromagnetic metamaterial. The gas chamber is a cubic gas chamber formed by bonding metamaterials with special electromagnetic performance, a first surface (1) and a third surface (3) which are parallel to each other are made of materials with ideal electrical conductor (PEC) characteristics, a second surface (2) and a fourth surface (4) which are parallel to each other are made of materials with ideal magnetic conductor characteristics (PMC), and a fifth surface (5) is a glass surface with high transmission performance, a sixth surface (6) opposite to the fifth surface has the characteristic of high absorptivity (Absorber) for electromagnetic waves, and if the sixth surface (6) contains the graphene material, the wave absorbing frequency of the sixth surface (6) can be dynamically tuned by using voltage. According to the atomic gas chamber with the structure, the Fabry-Perot cavity resonance condition formed by the para
