Summary :

A series of transverse electromagnetic transmission cells (TEM cells) developed at the National Bureau of Standards (NBS) is three-dimensional analyzed using a mixed discretization based on both of constant and linear elements in a boundary element method (mixed BEM). Mixed BEM presented here is generalized in order to be usable in two and three dimensions. Conductor surface of TEM cell models is discretized using non-uniform elements so that the flux distribution can be approximated more accurately in the less number of elements. The distributed characteristic impedance, which is important to design the cell, in the main line section is evaluated through the flux induced in the center conductor. The calculated results are in good agreement with those in two dimensions in spite of the small number of elements. As a result, it is proved that three-dimensional cell models are effectively and accurately solved by using mixed BEM and non-uniform elements together. The present work plays a preliminary part in an analysis of more realistic NBS cell models taken into account a tapered section. In future, therefore, we will be able perform a reliable analysis of TEM cells using mixed BEM and non-uniform elements.
