Application of finite element methods to photonic crystal modelling - Science, Measurement and Technology, IEE Proceedings-
Photonic Crystals (PCs) are materials with a pcriodically modulated dielectric constant, through wluch certain frequencies of electromagnetic radiation cannot propagate. The modes admitted by PCs can he investigated effectively using the finite element method with the assistance of the Floquet-Bloch theorem, by considering a unit cell of the material and imposing periodic boundary conditions. A...
متن کاملFinite Element Analysis of Photonic Crystal Fibers
Abstract. A finite-element-based vectorial optical mode solver, furnished with Bayliss-Gunzburger-Turkel-like transparent boundary conditions, is used to rigorously analyze photonic crystal fibers (PCFs). Both the real and imaginary part of the modal indices can be computed in a relatively small computational domain. The leakage loss, the dispersion properties, the vectorial character, as well ...
متن کاملAn Application of Finite Element Modelling to Pneumatic Artificial Muscle
The purpose of this article was to introduce and to give an overview of the Pneumatic Artificial Muscles (PAMs) as a whole and to discuss its numerical modelling, using the Finite Element (FE) Method. Thus, more information to understand on its behaviour in generating force for actuation was obtained. The construction of PAMs was mainly consists of flexible, inflatable membranes which having or...
متن کاملModelling photonic crystal devices using second order finite volume method
A second order finite volume scheme is considered [1]. The scheme includes total field scattered field formulation and a perfectly matched layer [2]. It was applied to evaluation of optical properties of photonic crystal waveguides [3]. Reflection and transmission coefficients were studied for a range of frequencies inside the photonic crystal bandgap for different configurations. Our results c...
