Research Areas of Electromagnetics • Antenas • Microwaves • Computational Electromagnetics • Electromagnetic Scattering • Electromagnetic Propagation • Radars • Optics • etc …
Electrostatics • Charges make E fields and forces • charges make scalar potential differences dV • E can be found from V • Electric forces move charges • Electric fields store energy (capacitance)
Magnetostatics • Currents make B fields • currents make magnetic vector potential A • B can be found from A • Magnetic forces move charges and currents • Magnetic fields store energy (inductance)
Electrodynamics • Changing E(t) make B(x) • Changing B(t) make E(x) • Wave equations for E and B • Electromagnetic waves • Motors and generators • Dynamic Sun
