Robust optimization in electromagnetic scattering problems
In engineering design, the physical properties of a system can often only be described by numerical simulation. Optimization of such systems is usually accomplished heuristically without taking into account that there are implementation errors that lead to very suboptimal, and often, infeasible solutions. We present a robust optimization method for electromagnetic scattering problems with large...
متن کاملIsogeometric Shape Optimization for Electromagnetic Scattering Problems
We consider the benchmark problem of magnetic energy density enhancement in a small spatial region by varying the shape of two symmetric conducting scatterers. We view this problem as a prototype for a wide variety of geometric design problems in electromagnetic applications. Our approach for solving this problem is based on shape optimization and isogeometric analysis. One of the major difficu...
متن کاملTopology optimization of periodic microstructure of electromagnetic material
1 Abstract This paper describes a topology optimization method for structures in electromagnetic materials. The material structures that exhibit special characteristics in terms of the repulsion of electromagnetic waves tend to be configured as periodical composite structures built of two or more materials. Generally termed “metamaterials”, these sometimes have especially unusual or even counte...
متن کاملElectromagnetic wave scattering by small perfectly conducting particles and applications
A rigorous theory of electromagnetic (EM) wave scattering by one and many perfectly conducting small bodies of an arbitrary shape is developed. Equation for the effective field is derived in a medium in which many small particles are distributed. A method is given to change the refraction coefficient of a given medium in a desired direction by embedding into this medium many small particles.
متن کاملVisualisation and Grid applications of electromagnetic scattering from aircraft
Electromagnetic scattering behaviour plays a central role in the design of aircraft and other complex structures. This paper describes progress on visualisation tools in this area and on initial development of a web portal to enable scientists at remote locations to collaborate.
