three-dimensional grating

Because changing the shape of cross sections of cylindrical gratings can alter the distribution of high-frequency field and strengthen the intensity of electromagnetic wave in the interaction area. Three shapes of cylindrical grating section are discussed, including the inverted trapezoidal cross-section, rectangular and trapezoidal cross-section.
