Transmission and diffraction properties of a narrow slit in a perfect metal
Transmission and diffraction properties of a narrow slit in a perfect metal
By solving Maxwell equations with the ideal-metal boundary conditions in the TM case, we have fully described the transmission and diffraction properties of a single slit regardless of its width. Efficiencies of the main transformation processes -- transmission, diffraction, and reflection -- are analyzed in the sub-to-few-wavelength range showing a …
