The so-called "real" part (e r ') is the relative dielectric constant, often introduced in electronics or physics courses in the context of capacitors. It is a storage component measured as capacitance per unit length. (Capacitance is "the amount of charge a material can hold" for a given applied voltage.) At different frequencies, polarization occurs at different scales: at very high ...
