Abstract
In this work, we tune the frequency of the resonant peak associated to extraordinary transmission phenomenon by changing slightly the topology of typical subwavelength square apertures. By substituting the vertical lateral walls for meander-lines it is possible to move the extraordinary transmission peak downward accompanied by an unprecedented enlargement of the fractional bandwidth. This phenomenon is theoretically analyzed from an equivalent circuit perspective and demonstrated experimentally at the millimeter-wave and mid-infrared band. A wide range of applications may benefit from this, since now the extraordinary transmission happens far away from the onset of higher order diffracted modes.
