Squematic and results of the equivalent circuit model.
(a), Physical meaningful equivalent circuit model. Z(air) and Z(Si) are the background material characteristic impedance. Lap models the aperture inductance, Zc(ω) the losses in the metal and C(air)(ω) and C(Si)(ω) the admittance of the below-cutoff TM01 mode excited at the air-metal and metal-silicon interface, respectively. The π-network of inductances Lp − Ls − Lp accounts for the thickness of the structure. (b), Field transmission results computed numerically (CST - solid lines) and via the equivalent circuit (EC - dotted lines).
