Abstract: We improved common metamaterial perfect absorber (MPA) by integrating four embedded inductors or replacing four embedded capacitors in the same compact structure. The obtained results confirmed that the lumped-capacitors MPA maintain an extreme thickness t = λ/940, where λ is operating wavelength at 106.3 MHz. Besides, by replacing these capacitors by inductors in the initial designed-MPA structure, we obtained an effective thickness of t = λ/53 at 1.9 GHz. Furthermore, we explained the absorption mechanism in terms of the magnetic energy and power loss distributions related to the impedance-matching effect.
