内容記述
A polarization converter using an array of subwavelength triangular holes is analyzed by the imaginary-distance beam-propagation method based on Yee's mesh and the finite-difference time-domain method. Optimum con_ guration parameters are determined using the eigenmode analysis. For a thickness of only 2.3 µm, the polarization converter acts as a half-wave plate over a wide wavelength range of 1.2 µm to 1.8 µm. The polarization converter becomes a quarter-wave plate in half the thickness.
