Electromagnetic Fields in Linear and Nonlinear Chiral Media: a Time-domain Analysis
We present several recent and novel results on the formulation and the analysis of the equations governing the evolution of electromagnetic fields in chiral media in the time domain. In particular, we present results concerning the well-posedness and the solvability of the problem for linear, time-dependent, and nonlocal media, and results concerning the validity of the local approximation of t...
متن کاملTime-harmonic Electromagnetic Fields in Thin Chiral Curved Layers
In this paper, we prove existence and uniqueness of the solution to the diiraction problem of a plane electromagnetic eld by a chiral curved layer covering a perfectly conducting object. Approximative impedance conditions are given for thin chiral curved layers and optimal error estimates are obtained.

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Electromagnetic Scattering From Chiral Media
Time and frequency domain analysis of electromagnetic plane wave scattering from chiral media are presented. The frequency domain solution deals with two-dimensional scatterers using a boundary value and an iterative techniques for the scattering from a number of parallel circular cylinders forming a scatterer of arbitrary cross-section. The time domain solution is based on a scattered field fi...
متن کاملElectromagnetic Characterization of Chiral Media
During recent decades, a great variety of novel and complex materials have been designed with promising practical applications. It has been found, however, that in many cases the relations between electric and magnetic fields cannot be described by standard constitutive equations. Among these new materials we may mention, for example, chiral, nonreciprocal, gyrotropic and negative refractive in...
