The present disclosure relates to transverse magnetic wave (TM) mode filters and methods for manufacturing a TM mode filter. One example TM mode filter includes a filter body, a dielectric, and a transition layer, the filter body including a filter cavity and a cover, and having hollow confined space, the dielectric located in the hollow confined space, and the transition layer configured to connect the dielectric and the filter body. A coefficient of thermal expansion (CTE) of the transition layer is between a CTE of the filter body and a CTE of the dielectric.
