I am a career EE, with a couple of graduate EE degrees;
and this is something entirely new to me. Could you explain
this concept, and/or provide some references?

How about an example? If L and C are lossless, then SQRT(L/C)
will be lossless with a dimension of ohms, i.e. resistance.

Umm, isn't that an example of reactance? I assume you would have us
believe they are one in the same. BTW, not all forms of resistive loss
are "ohmic".
