Abstract
The guided dispersion characteristics of surface plasmon polaritons (SPPs) through subwavelength plasmonic holes (SPHs) in metals are investigated with an emphasis on their single- mode operations. Using a characteristic equation without any modifications, we obtained the dispersion curves of SPPs for several diametric SPHs, thereby providing a variety of information, such as the dispersions, the allowed spectral ranges, the cutoff frequencies, the wave velocities, and so on. The significant effect of SPH diameter on single-mode operations is analyzed.
