Off-center coaxial waveguide
Off-center coaxial waveguide
(OP)
I am looking to characterize a coaxial waveguide in which the inner conductor is off-center. Is it still TEM mode? How do I calculate impedance and wavelength?

In this book, the Formula for eccentric round coaxial line is also given - Hummmm - well - ??? It would take a little time to put the explaniations here without a diagram.
A quick Google search for "Eccentric Round Coaxial Line" got a few hits which looked somewhat like the formula.
RE: Off-center coaxial waveguide
What you describe isn't a waveguide in the truest sense. Waveguide is a balanced feed device and coaxial cable is unbalanced. (remember, waveguide acts like twin-lead with an infinite number of ?/4 stubs connecting the two conductors...Oh, to be able to draw a picture.)
