"WebAt microwave frequency impedance is measured as a vector, with magnitude, real and imaginary parts. The impedance rotates as you move away from it, just like it does for a coaxial transmission line. The impedance of an object is not well defined but a measurement of the material will tell if it will heat. Sponsored by The Penny Hoarder " - Microwave impedance measurement
