Performance of customizable cut-wire-based (CW-based) metamaterial absorbers is studied both numerically and experimentally. In the first part of the paper the fundamental absorbing performance of the CW-based metamaterial absorbers is numerically investigated. In this paper two simple geometrical modifications are proposed to easily enhance the absorbing performance: use of geometrical symmetries and wider CWs. The latter part of the paper shows an experimental demonstration of the CW-based metamaterial absorbers using a metal box lined with metamaterial absorber. The metal box has a resonant frequency which reduces the shielding effectiveness of the metal box but disappears when multiple CW absorbing elements are introduced. The absorbing performance is also confirmed by numerical simulations. The CW-based metamaterial absorbers have several important features, e.g., the simple geometry, both arbitrary enhancement and reduction of the absorbing performance and multiple band operation, which may be useful in satisfying a wide range of wave absorber applications.
