Study on frequency selective characteristics of the microstructure metallic grating in terahertz frequency range based on the hybrid implicit explicit‐pseudospectral time domain method

Abstract: In this paper, a hybrid implicit explicit-pseudospectral time domain method is presented to simulate the microstructure metallic grating. The time step size in this method has no relation with the fine spatial discretization, and the spatial discretization along the electrically large direction only needs two cells per wavelength. The three-dimensional formulas of the method are presented, and the time stability condition of the method is demonstrated. Numerical results show that the memory requirement of the … Show more

“…Frequency‐selective surface (FSS) has been a hot research topic for several decades because of its superior reflection or transmission characteristics . It has found many applications, for example, airborne radomes, absorbers, antenna reflectors, and electromagnetic band gaps. Nevertheless, conventional FSS is sensitive to not only the frequency, but also the incident angle of the electromagnetic wave.…”
