WebSep 11, 2005 · The filters are usually tubular or square cavity type filters but other types of construction such as combline, ceramic, etc. may also be used in some cases. Cavity type filters offer the best overall balance of performance, simplicity and costs. Combline and ceramic filters have some space and size advantages at higher frequencies. WebGMRs, cavity modes and SPPs dominate this resonant dip. For the dip λ 3, only weak electric field is found in the grating slots and the two Si films and the magnetic field is mainly concentrated in the SMS stacks [Figs. 1(g) and 1(h)]. It can be concluded that this dip is closely related to the cavity modes and SPPs.20–22)
