Electromagnetic radiations of small circuits and their effective control

The precise behaviors of the sinusoidal components of a periodic current in a small circuit are rather involved to predict. As a result, the electromagnetic radiations of those components are also rather involved to predict. Nevertheless, it is relatively easy to see that (a) circuit-current phase differences cannot be neglected in predicting their radiations, no matter how small the circuit may be, and (b) circuit-current radiations must be controlled not by simply minimizing circuit area, but by minimizing circuit width-the distance between the forward and return currents paths
