We explain modal processes in 2-D guided-mode resonance reflectors with subwavelength periods in terms of the mode structure of quasi-equivalent 1-D gratingbased reflectors. The 1-D gratings are designed via a second-order ...

Using the developed discrete dipole approximation method, we investigate the behavior of silicon nanodisks acting as Huygens sources. First, we study the correlation between the radius of a silicon nanodisk and its electric ...

Resonant leaky modes can be induced on dielectric, semiconductor, and metallic periodic layers patterned in one or two dimensions. Potential applications include bandpass and bandstop filters, laser mirrors, ultrasensitive ...
