Specific absorption rate (SAR) is computed using the finite element method (FEM) embodied in Ansoft HFSS. Comparisons to finite difference time domain (FDTD) simulations and measurements show that accurate results can be obtained using FEM. High-fidelity models using standards-compliant phantom models are demonstrated and benefits of FEM are highlighted.
Commercial electromagnetic (EM) software combined with circuit and system simulation was applied to characterize transmission lines, vias and connectors for systems that incorporate high-speed serial transmission. Two-dimensional EM simulation was used to extract quasistatic circuit models for the PCB transmission lines; three-dimensional EM simulation was(More)
Tile self-assembly systems serve as models of DNA molecules designed to act as foursided building units that can self-assemble to various shapes. Research on the design of such nanoscale constructs has shown their high potential usefulness in the area of nanotechnology. Given a target shape of tiles, the goal is to find the tile set that will selfassemble(More)
An automated solution for electromagnetic (EM)/circuit co-design is discussed and demonstrated. Examples using a low-temperature co-fired ceramic (LTCC) circuit is given. It is shown that design of complex high-frequency structures can be greatly enhanced by coupling three-dimensional (3D) electromagnetic field simulation with traditional circuit and system(More)
