From: Ultrabroadband microwave metamaterial absorber with dielectric lossy layer
The effective complex impedance of the absorber with different resistive ink coating thicknesses (\(\:{t}_{4}\)= 0, 2, 6, 10, 14, and 18 \(\:\mu\:\text{m})\) and heights (h = 2, 3, 4, 5, and 6 mm). (a, c) real part and (b, d) imaginary part of the complex impedance.
