Abstract:
This paper analyses the principle and process to solve the diffraction efficiency of gratings with binary simple period structures by applying vectorial theory and explores a method to design a high-performance even-beam splitter. By programming, we obtain an even splitter with a binary structure in the Terahertz range. Thus, the zero-order diffraction is suppressed effectively, and it breaks the design limit of the traditional scalar theory. In addition, we discuss the physical mechanism of the method to suppress the zero-order diffraction by resolving the energy to the non-zero-order diffractions due to the resonance effect and the evanescent wave propagation effects.
