The history of ceramic filters

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2000
The history of ceramic filters is surveyed. Included is the history of piezoelectric ceramics. Ceramic filters were developed using technology similar to that of quartz crystal and electro-mechanical filters. However, the key to this development involved the theoretical analysis of vibration modes and material improvements of piezoelectric ceramics ...

On The Modelling Of Ceramic Combline Rf-filter

27th European Microwave Conference and Exhibition, 1997
In order to design filters effectively, it is necessary to be able to predict frequency characteristics of a certain kind of filter structure suitably fast. Considering ceramic filters, instead of 3-D field analysis program, a circuit simulator program is often a good choice for a modelling tool, especially in the early stages of new filter design.

Filtering diesel exhaust gases with ceramic filters

Chemical and Petroleum Engineering, 2008
Results are given from three test series on a ceramic filter for diesel exhausts. In the first and second series, use was made of diesel fuel (in the summer), while in the third series, we used the Standard Euro-4 fuel. A grain-size analysis is given for the dust.
