Time and Phasor Domain
It is much easier to deal with exponentials in the phasor domain than sinusoidal relations in the time domain Just need to track magnitude/phase, knowing that everything is at frequency ω

Maxwell’s Equations
Sinusoidal time variations
Materials: ε, µ - time independent, isotropic, homogenous, linear

Static vs. Dynamic Static conditions: (a) charges are stationary or moving, but if moving, they do so at a constant velocity (b) size of system much smaller than a wavelength
Under static conditions, electric and magnetic fields are independent, but under dynamic conditions, they become coupled.
