Abstract
Using CST, a LTCC (Low Temperature Co-fired Ceramics) technology basing design of the metamaterial absorber in terahertz region (MM) is proposed. The metamaterial absorber is constructed by silver plane and a specially designed ERR structure. The investigation to the electric field, surface current and absorption power density distribution indicates that the metamaterial absorber we design is somewhat different from the ones have been proposed, the reason of which is thought to be the wide line width comparing to the working wavelength, however, the working mechanism is consist with the one we has reported. And we have also pointed out the EM characteristic and thickness of the isolation layer is crucial in obtaining the unit absorption.
