The obtained results confirmed that the lumped-capacitors MPA maintains an extreme thickness <em>t </em>= 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 <em>t</em> = 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.</p>}, number={5}, journal={Vietnam Journal of Science and Technology}, author={Lam, Tran Tien and Nga, Dinh Thi and Thien, Dinh Van and Khiem, Nguyen Sy and Khuyen, Bui Xuan and Tung, Bui Son and Lam, Vu Dinh}, year={2020}, month={Oct.}, pages={571–577} }
