ABSTRACT The spectral and spatial treatment of electromagnetic fields express an essential operation regarding the functionality of integrated optical devices. Such molding of fields can hardly be handled without sophisticated heuristic optimization tools. We propose evolutionary algorithm schemes being canonical by investigating numerous design examples in(More)
Particle-based simulations running on large highperformance computing systems over many time steps can generate an enormous amount of particle- and field-based data for post-processing and analysis. Achieving high-performance I/O for this data, effectively managing it on disk, and interfacing it with analysis and visualization tools can be challenging,(More)
This article presents the RF characterization results of a large-area MCM-D technology developed within the EU LAP project. Microstrip lines were simulated, designed, and manufactured in several material combinations. Measurements up to 120 GHz showed good coincidence between simulation and reality. Future work is dedicated to filters and antennas in the 77(More)
We introduce a 3-dimensional electromagnetic eigenmodal algorithm for the theoretical analysis of resonating nano-optical structures. The method, a variant of the Jacobi-Davidson algorithm, solves the electric field vector wave, or curl-curl, equation for the electromagnetic eigenmodes of resonant optical structures with a finite element method.

ABSTRACT – The spatial and spectral treatment of electromagnetic fields express an essential operation regarding, e.g., the functionality of dense integrated optical devices. Such molding of fields can hardly be handled without sophisticated heuristic optimization tools. By means of five design examples we have demonstrated that evolutionary algorithms (EA)(More)
Two dedicated RF test vehicles (RF-TV) have been designed to characterise the high frequency performance of a new low-cost thin film (MCM-D) technology, fabricated on large area panels (LAP). Previous investigations revealed the capabilities of the new LAP technology to be used at frequencies up to 110 GHz. Test structures for transmission measurements,(More)
We introduce the dune-curvilineargrid module. The module provides the self-contained, parallel grid manager dune-curvilineargrid, as well as the underlying elementary curvilinear geometry module dune-curvilineargeometry. Both modules are developed as extension of the DUNE [3] project, and conform to the generic dune-grid and dune-geometry interfaces(More)
