Resumen
In this paper Anomalous Extraordinary Transmission (ET) is
reported for s-polarization of low loss doubly periodic subwavelength hole
arrays patterned on polypropylene (PP) substrates by conventional contact
photolithography at the so-called THz-gap (1-10 THz). The unexpected
enhanced transmittance for s-polarization (i.e. without spoof plasmons) was

In this paper Anomalous Extraordinary Transmission (ET) is
reported for s-polarization of low loss doubly periodic subwavelength hole
arrays patterned on polypropylene (PP) substrates by conventional contact
photolithography at the so-called THz-gap (1-10 THz). The unexpected
enhanced transmittance for s-polarization (i.e. without spoof plasmons) was
previously numerically demonstrated in subwavelength slits arrays.
However, subsequently no experimental work has been devoted to this
unexpected Extraordinary Transmission neither in subwavelength slits nor
in subwavelength holes. Here, numerical study and experimental results of
the Anomalous ET and the symmetric and antisymmetric transmittance
modes associated with the already well-known p-polarization ET are shown
alongside a systematically analysis of the frequency peaks as a function of
hole size for both incident polarizations. [--]
