A metamaterial absorber is realized for microwave and terahertz ranges using two-dimensional bianisotropic omega-elements by thorough analysis of their distribution on substrate as well as properly choosing omega's geometrical and material parameters. Simulations and experimental studies of the metamaterial confirm its low reflectance in a wide microwave range and high absorbance at the resonance.
