Optical characterizations of multi-shape nanoparticles in polymer thin film layers

Carlberg M., Pourcin F., Margeat O., Le Rouzo J., Berginc G., Sauvage R.-M., Ackermann J., Escoubas L., Aix Marseille University, FR

Metallic nanoparticles are currently a hot topic thanks to their tuneable optical properties. Indeed, their light absorption or scattering is material, size and shape, but also environment dependent. We aim to take advantage of these [...]

System-Level Optical Interface Modeling for Microsystems

Kurzweg T.P., Sharma A.S, Bhat S.K., Levitan S.P., Chiarulli D.M., Drexel University, US

In this paper, we present an accurate and computationally efficient system-level optical propagation technique suitable for the modeling of optical interfaces. Our technique is based on extensions to the angular spectrum technique used to solve [...]

Magnetic Diffusion in Nonlinear Micro-Media: A Modified Finite-Difference Time-Domain Approach

Cros F., Allen M.G., Lang J.H., Massachusetts Institute of Technology, US

As flux densities and frequencies are raised to increase the performance of magnetic micro-actuators, micro-motors/generators, and micro-inductors, eddy currents and magnetic saturation start to limit the performance of these devices. In this paper, we present [...]

Large Scale FDTD Simulation for Microoptics and Metamaterial Investigations – Current Possibilities and Verification Benchmarks

Hieke A., Tramel R., CFD Research Corporation, US

The study of microsystems containing photonic crystals (PC) and meta-materials are rapidly growing fields of research. Finite-Difference Time-Domain (FDTD) full wave electromagnetic solvers are now increasingly used to investigate and design such systems. However, in [...]

Dispersive Media in FDTD-Comparison of Recursive Convolution and Auxiliary Differential Equation Methods

Körner T.O., Fichtner W., ETH-EPFL, CH

A new, efficient algorithm for modelling dispersive media in Finite Difference Time Domain (FDTD) methods is presented. It is based on the Auxiliary Differential Equation (ADE) formulation. Accuracy and efficiency are compared to other ADE [...]
