ABSTRACT
Non-bold italic symbols are employed here to denote scalars or time variables (e.g., a voltage signal in the time domain will be noted as V(t) or V). Bold italic symbols are employed for complex variables (e.g., the Fourier transform of a voltage signal V(t) will be noted as V(ω) or V). On the other hand, bold non-italic symbols are employed for vectors such as the electric eld, E, and the current density, J.
