Non-dissipative resistance is not well accepted or understood by many otherwise
well informed engineers, because it has had little or no (or even incorrect)
treatment in EE courses.

Yet the IEEE recognizes those two types of resistances with different definitions.
Definition (A) talks about "dissipation or other permanent loss". Definition (B)
simply says "The real part of impedance." Then a note: "Definitions (A) and (B)
are *NOT* equivalent ..." (emphasis mine)

The resistance in a resistor satisfies definition (A). The characteristic
impedance of a transmission line satisfies definition (B).
