研究目的
To propose an innovative effective medium model for the simulation of 1D-periodic subwavelength metal–dielectric laminated structures excited by TM- or TE-polarized plane waves with oblique incidence angles, and to compute the transmission and reflection coefficients and the shielding effectiveness of such structures.
研究成果
The proposed effective medium model based on the transfer matrix method accurately simulates 1D-periodic subwavelength metal–dielectric laminated structures excited by TM- or TE-polarized plane waves with oblique incidence angles. The model allows for the homogenization of n-layer periods and demonstrates good accuracy in computing transmission and reflection coefficients and shielding effectiveness compared to the rigorous multilayer model. This approach simplifies the simulation of complex multilayered thin shielding structures in the very high frequency range.
研究不足
The model assumes that each film of the laminated structure is electrically thin in the frequency range up to 10 THz, which may not hold for all materials or higher frequencies. The study focuses on TM- and TE-polarized plane waves with oblique incidence angles, potentially limiting its applicability to other polarization states or incidence conditions.
