Abstract
We examine ways in which pulses of electromagnetic radiation can be collimated at low energies. Simple consideration of geometric spreading implies that, for an idealized monopole point-source of radiation, emanating outward equally in all directions, the measured intensity should fall off with an inverse square law. Dipole sources would fall off more rapidly, with an anisotropic distribution. Higher-order sources fall off even more rapidly, with their own characteristic angular distribution. We seek to investigate how tailored combinations of sources will distribute their combined radiation fields, and how the net signal strength will diminish with distance from the sources. There are many applications which depend upon directional control of radiation. At higher energies, work must involve added safety considerations, including the use of careful shielding and grounding.
