Abstract- We develop a new causal power-
normalized waveguide equivalent-circuit theory that,
unlike its predecessors, results in network
parameters usable in both the frequency and time
domains in a broad class of waveguides. Enforcing
simultaneity of the voltages, currents, and fields and
a power normalization fixes all of the parameters of
the new theory within a single normalization factor,
including both the magnitude and phase of the
characteristic impedance of the waveguide.
INTRODUCTION
We develop a causal power-normalized waveguide
equivalent-circuit theory. The theory determines
voltages, currents, and network parameters suitable for
use in both frequency- and time-domain circuit
