The damping properties of surface polaritons, especially long-range surface plasmon-polaritons (LRSP) in asymmetric layer structures are analyzed taking into account the presence of a coupling prism. Both, the response treatment to calculate attenuated-total-reflection (ATR) spectra and the virtual mode treatment are used. Two different types of virtual modes are analyzed. One of them describes the propagation properties of the surface polariton in the presence of both intrinsic and radiative damping. The other type describes a surface polariton with a driving field and hence this mode allows to find out the optimum conditions for the ATR experiment. These two modes are investigated in detail and the results of the numerical calculation are presented in graphical form. The results for the ATR configuration show that in asymmetric embedded silver layers the propagation length exceeds the value for the symmetric embedded one significantly.
Es werden die Dampfungseigenschaften von Oberflachen-Polaritonen, speziell Langstrecken-Oberflachen-Plasmon-Polaritonen in asymmetrischen Schichtstrukturen unter Einbeziehung der Existenz eines Koppelprismas analysiert. Es werden sowohl die Response-Theorie zur Berechnung der abgeschwachten Totalreflektionsspektren als auch das Konzept der virtuellen Moden verwendet. Zwei verschiedene Typen von virtuellen Moden werden analysiert. Eine von beiden beschreibt die Ausbreitungseigenschaften eines Oberflachen-Polaritons beim Vorhandensein sowohl von intrinsischer als auch Strahlungsdampfung. Der andere Typ beschreibt ein Oberflachen-Polariton mit einem oszillierenden Feld, womit es diese Mode ermoglicht, optimale Bedingungen fur ein Experiment der abgeschwachten Totalreflektion zu finden. Diese beiden Moden werden detailliert untersucht und die Resultate numerischer Rechnungen graphisch dargestellt. Die Ergebnisse fur eine Konfiguration zum Experiment der abgeschwachten Totalreflektion zeigen, das in asymmetrisch eingebotteten Silberschichten die Ausbreitungslange den Betrag fur die symmetrisch eingebettete Silberschicht deutlich uberschreitet.read more

TL;DR: It is provided definitive evidence that the reflectance dip in K-R experiments does not correlate with excitation of an SPP mode, but rather corresponds to a particular type of perfectly absorbing (PA) mode.
