The transmission of normally incident plane wave microwaves through a single stepped subwavelength slit in a thick metal plate is explored. The presence of the step substantially increases the radiation wavelength which may be resonantly transmitted to well beyond twice the plate thickness. Insight into the resonant behavior is provided through analysis of field solutions produced by a finite element model.
