How does Twinax work?

HPRF

Hi,

I am investigating a device that I think shows similar properties to twinax, but I am unable to find any theory on it.

Does anyone know of any websites or books that explain the theory behind twinax; equivalent circuits of twinax would be especially helpful...

Thanks in advance,

Daniel

Hi,

I don't think the previous message was clear enough.

What I am looking for is theory that describes the interaction between the the two individual coax's in twinax.
