On the applicability of conventional transmission line theory within cavities [PDF]
Advances in Radio Science, 2006 We investigate whether or not conventional transmission line theory needs to be modified if transmission lines are considered that are located in a cavity rather than in free space.

High-Sensitive Parity-Time Symmetric Oscillator in Coupled Transmission Lines With Nonlinear Gain
IEEE Journal of Microwaves, 2022 A scheme for generating oscillations based on an exceptional point of degeneracy (EPD) is proposed in two-coupled resonators made of two coupled transmission lines terminated on balanced gain and loss, exhibiting a double pole.

COUPLED TRANSMISSION LINES [PDF]
, 1959 >Tests on a coupled transmission line resonator show that a fairly accurate value of the coupling coefficient can be predicted by considering line geometry. The measured values of V/sub 02/ and I/sub 02/ appear to agree with predicted values. Development of a resonator for ORIC with two coupled transmission lines is under way. (W.L.H.)
