Schematic of the metallic (aluminum) gratings. Slit width is 2 mm, slit length between the interfaces is 8 mm, and groove depth is 4 mm. Grating periods of the back and front sides are denoted by and , respectively.
Calculated transmission for samples A–C at . Illumination side is specified in brackets.
Experimental and simulated transmission results for sample A at .
Experimental and simulated angular distributions of transmission at for sample A at . Positive angles represent the right-hand side of the structure, while negative angles represent the left-hand side of the structure.
Experimental and simulated angular distributions of transmission at for sample B at .
