We present the design and characterization of a three-dimension metamaterial consisted Jerusalem cross unit cell on each side cube lattice substrate for terahertz frequencies. The retrieved effective medium parameters from scattering data prove that has negative permeability permittivity in wide frequencies range 1.47-1.73 THz. demonstrate can be regarded as polarization insensitive absorber with an absorptivity 46% at 1.49 Such designed materials may find numerous applications ranging active element thermal detector to stealth technology.
