چکیده

Plasmonic structures based on stacked layers of metal and dielectric materials excel as broadband absorbers because the nonlinear relationship between compound materials’ dispersion characteristics multilayered structure’s actual performance. In this work, radiation absorption along plasmonic absorber is studied. Broadband absorptance spectra play an important role in applications such photovoltaics, detectors, modulators, emitters. We propose analyze that exhibit high absorption. For purpose, inverse design approach has been implemented using a conventional genetic algorithm global optimizer conjunction with pattern search local optimizer. The proposed strategy found covering visible spectrum, maintaining its performance for incident angles.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Structurally tunable resonant absorption bands in ultrathin broadband plasmonic absorbers.

Light absorption is a fundamental optical process playing significantly important role in wide variety of applications ranging from photovoltaics to photothermal therapy. Semiconductors have well-defined absorption bands with low-energy edge dictated by the band gap energy, therefore it is rather challenging to tune the absorption bandwidth of semiconductors. However, resonant absorbers based o...

Theory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures

A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite bounding media where each layer may have a frequency dependent dielectric function and ...

Spatial Domain Green’s Functions for Planar Multilayered Structures

This paper presents a robust approach for calculating spatial-domain Green’s functions on the interface or close to the interface of planar multilayered microstrip structures with lossless or lossy dielectric materials for a wide range of frequencies and layer thicknesses. We compute the mixed potential Green’s functions for distance for 200 points from 0.1 to 10 wavelengths. The CPU is less th...
