Abstract :
In this paper, several structures that allow for optical, terahertz, and microwave enhanced transmission phenomena through metal plates perforated by arrays of holes of subwavelength cross-section are investigated. It is shown that the transmission enhancement is associated with resonant coupling between the incident/transmitted field and source-free fields supported by the perforated plate. The source-free fields are allowed when any type of slow waves is supported by the plate and a proper periodic arrangement of the subwavelength holes is present.
