To derive an exact classical electrodynamic formulation that relates the radiation intensity, angular momentum loss, and recoil force of an arbitrary source to its complete electromagnetic multipole structure.
Analytically calculated radiation emission, angular momentum loss, and recoil force for general charge-current configurations with arbitrary time dependence.
Formulated expressions incorporating electric, magnetic, and toroidal multipole moments alongside the mean radii of their spatial distributions using time derivatives.
Provided an exact analytical solution linking the radiation properties of any electromagnetic source directly to its internal charge and current distributions.
Identified corrections to conventional textbook radiation formulas caused by toroidal multipole moments and their interference with standard electric and magnetic multipoles.
