As the plasmonic scatterers get much smaller than the wavelength of the incident light, local material models like the Drude model and the Lorentz model become inadequate to describe accurately the light-matter interactions. To overcome this, a sophisticated nonlocal hydrodynamic Drude model is investigated. In practice, it is further simplified and simulated with the curl-free approximation, w...

In this paper the Finite Element Method is employed for the analysis of electromagnetic lossless waveguides. The curl-curl equation, deduced from Maxwell equations, is solved for the electric eld. We have studied the appearance of parasitic solutions and formulated a suucient condition for their elimination which puts a contraint on the Finite Element spaces for the approximation of the eld com...

SUMMARY In this paper an inverse scattering problem for the time-dependent Maxwell curl equations is considered. This problem is formulated as an optimal control problem governed by partial differential equations. First-order necessary optimality conditions are discussed. For the numerical solution a gradient-based algorithm is applied and successfully tested for some numerical examples. Finall...

In this paper we prove an optimal error estimate for the H(curl)-conforming projection based p-interpolation operator introduced in [L. Demkowicz and I. Babuška, p interpolation error estimates for edge finite elements of variable order in two dimensions, SIAM J. Numer. Anal., 41 (2003), pp. 1195–1208]. This result is proved on the reference element (either triangle or square) K for regular vec...

The genome of tomato leaf curl virus (TLCV) from Australia was cloned and its complete nucleotide sequence determined. It is a single circular ssDNA of 2766 nucleotides containing the consensus nonanucleotide sequence present in all geminiviruses. It has six open reading frames with an organization resembling that of certain other dicotyledonous plant-infecting monopartite geminiviruses, i.e. t...

The analysis of electromagnetic (EM) scattering in the isogeometric (IGA) framework based on Loop subdivision has long been restricted to simply connected geometries. inability analyze multiply objects is a glaring omission. In this article, we address challenge. IGA provides seamless integration between geometry and using same basis set represent both. particular, methods sets exploit fact tha...
