Fractional-rational representation of the frequency spectrum of the scattered field for a Drude-metal nanowire resonating on localized surface plasmons / M. V. Andreev, O. O. Drobakhin, N. P. Stognii, N. K. Sakhnenko // XXII International Seminar/Workshop DIPED-2017, September 25-28, 2017. – Dnipro, 2017. – P. 53-57.http://openarchive.nure.ua/handle/document/5181The paper discusses the problem of determining the eigenfrequencies of surface plasmons for metal nanowire over the frequency spectrum of the scattered field. To determine the eigenfrequencies a fractional-rational approximation of the frequency spectrum based on continued fractions was used. Q-factors for lower and higher modes of the localized surface plasmons are investigated.enPlasmon resonancelocalized surface plasmonfractional-rational approximationQ-factorConference proceedings
