### 摘要

In this work, we propose a filter structure using a one-dimensional ferroelectric-dielectric periodic multilayer, air/[(ABA)^{Ns},C]^{Np}(ABA)^{Ns}/air,where N_{s} and N_{p} are the two numbers of periods. Here, B is a dielectric material of SiO_{2}, C is the same as B with a different thickness, and A is taken to be a ferroelectric material Ba_{55}Sr_{45}TiO_{3} + 30%Mg_{2}SiO_{4}, whose dielectric constant is very high (ε = 439 at 10 GHz). The results show that the transmittance spectra have N_{s}-channel groups at microwave frequencies and these groups can be classified into two types. The first type has only one channel group with N_{p} narrower channels. The other has N_{s} - 1 groups, each of which has N_{p} + 1 broader channels. In this filter structure the group number and channel number of each group can be determined simply by changing N_{s} and N_{p}.
