Within the framework of a method-of-moments algorithm, the natural frequencies and natural modes of a scatterer/antenna can be found by looking for the complex frequencies where the determinant of the impedance matrix becomes zero.However, for nanotopologies, the value of Figure Skating - Boots - Mens this determinant can easily go beyond the resolution or representation limits available on present-day computers.In this work, we KAVA KAVA LIQUID propose a substitute for the matrix determinant that avoids this problem altogether: the characteristic term.

A robust numerical procedure for locating natural frequencies using this new target function is outlined.Then, the natural frequencies of three different nanostructures, namely, a gold and nickel nanopatch and a gold nanodimer, are calculated and validated by numerically and experimentally obtained scattering/extinction spectra.
