Bethe's theory is applied to the optical transmission through an array of apertures in an infinitely thin perfect electric conductor. This method shows that, in the small-aperture limit, the lowest-order TM evanescent mode governs the transmission process, allowing for both 100% transmission at the passband wavelength and zero transmission at the Wood's anomaly. The applicability of this theory to total transmission in other systems is discussed, and a specific example of a single aperture in a transverse screen of a rectangular waveguide is given.
