Ultra-compact spatial filtering with both wide spatial-frequency bandwidth and high transmittance using single-negative material

A new application of multilayer structures containing single-negative material is proposed as spatial filter. The spatial filter has an ultra-compact structure (only two periods) and is based on that the transmittance of waves through the structure is not sensitive to the incident angle. Through opt...
