Talk:TEM cell

Is a GTEM cell distinctly different?

Please provide reference to scientific literature on GTEM cell, which appears to be more of a branding for GHz operation. As maximum frequency of operation is related to onset of higher order modes and absolute dimension of the structure, a "GHz" TEM cell only needs be distinguished as such if it is in some way unusually designed, i.e. offering higher frequency operation than a conventional TEM cell of the same geometry. A reference to a scientific publication or patent would be helpful to properly distinguish a GTEM cell. 2610:148:610:2B06:0:0:0:28 (talk) 14:20, 14 December 2022 (UTC)
