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.)

General Conditions to Realize Exceptional Points of Degeneracy in Two Uniform Coupled Transmission Lines [PDF]
IEEE transactions on microwave theory and techniques, 2020 We present the general conditions to realize a fourth-order exceptional point of degeneracy (EPD) in two uniform (i.e., invariant along $z$ ) lossless and gainless coupled transmission lines (CTLs), namely, a degenerate band edge (DBE).
