In this letter we present an in-depth circuit analysis of anomalous extraordinary transmission ET
through subwavelength slit and hole arrrays loaded by a dielectric slab. We show the key role played
by the thickness of the dielectric slab in order to enhance the transmission for TE-polarized waves
incident electric field parallel to the slits or to the short in-plane period in hole arrays arranged in
rectangular lattice within the cut-off regime of the apertures and to suppress Wood’s anomaly.
Analytical and numerical results together with experimental data are presented, showing good
agreement among them. This work provides physical insight of the underlying mechanism
governing anomalous ET and offers further independent control over orthogonal polarized waves
impinging into subwavelength aperture arrays. [--]
