Bounds on Wave Scattering
Resonance phenomena enable many of the strongest wave–matter interactions in physics. We recently developed an analytical technique, based only on power-flow and energy-conservation considerations, that yields a new class of single-frequency and broad-bandwidth limits to resonant enhancement of the scattering properties of any structure. The method was originally motivated by plasmonic design—at optical frequencies, metals enable exciting plasmonic and metamaterial behavior, but also introduce dissipative losses—where they resolved a fundamental question about the extent to which losses can be suppressed while achieving strong, subwavelength resonances.
