Webtransmission grating structure shown in Fig. 1 a , consisting mode. We simulate the transmission of light through this structure using a finite element method program.15 To best demonstrate the excitation of an SP mode at 340 nm, which occurs at the silica/Al boundary, we illuminate the structure Webthat such a structure supports a bound mode in a wide frequency range. Within this range this mode has a wave vector larger than all radiation modes in air and silica, as well as all propagating modes in the air–silver–silica thin film structure. The cutoff fre-quency of this mode is 0.005 2 c/w, where c is the speed of light in free space.
