Abstract
The transmission characteristics of small slots and circular apertures in conducting films are described using a waveguide mode analysis and numerical simulations. A set of modes are shown to exist for a circular waveguide hole which propagate for an arbitrarily small diameter. As the hole becomes small, loading with a dielectric allows for low loss over a significant wavelength range.
