Numerical algorithms for modeling hybrid surface plasmon polaritons guided by metal films

Abstract

This paper presents an application of the numerical algorithms, based on Davidenko's method. The method has been found to be an efficient technique used to model the properties of hybird surface plasmon polaritons guided by an ultra‐thin metal film. A general computer program capable of providing the modeling of the mode effective index and the propagation loss (normalized attenuation constant) is written and implemented. Davidenko's algorithms allows us to obtain accurate numerical results in a very reasonable CPU time. The presented results could be useful in designing guided‐wave photonic devices based on materials with relatively large absorptive losses. © 1997 John Wiley & Sons, Inc.

Investigation of the Leaky-Wave Characteristics of a Cylindrical Dielectric Rod Using the Coefficient Matrix of the System of Characteristic Equations and Davidenko’s Method

“…Davidenko's method is a robust technique used to compute the complex roots of analytical functions. Davidenko's method has been used for electromagnetic problems in various studies [32,36,41,[48][49][50][51][52][53][54]. Kim et al studied the leaky-wave characteristics of TM and TE modes for cylindrical dielectric rods using closed dispersion equations of the structure and Davidenko's method [32,36,41].…”

E-beam assisted fabrication of a subwavelength aluminum mesh

“…Mihalache et al have considered the SPP guided in lossless structures involving a thin metallic layer [5] . Shabat extended the study by introducing complex indices and using the numerical algorithms of Davidenko's method to model SPP guided by a structure involving lossy thin metallic films and dielectrics [6] . This technique can be used to design low loss thin film photonic devices based on materials with large absorption properties.…”
