【英文介紹】
Aether is one of the most advanced programs available for 3D electromagnetic fields at a fraction of the cost of competing products. The unified finite-element package handles all stages of a solution: mesh generation, field calculation and interactive analysis. The program has three modes of operation that cover the spectrum of applications:
Pulse mode: EMI and end-to-end simulations of pulsed-power devices.
Res mode: Resonant frequencies and Q factors of 3D structures.
RF mode: Fast frequency-domain simulations of microwave and RF devices.
Features
Interactive, graphical mesh generation with import from SolidWords, AutoCAD and ProE.
Postprocessor features an interactive analysis environment with 2D and 3D graphics.
Define time-dependent conductivities for switch simulations.
Set continuous spatial variations of dielectric constant, magnetic permeability and conductivity from mathematical functions.
Preload electrostatic solutions to initialize charged transmission lines and capacitors.
Definition of complex 3D drive coils with the MagWinder utility.
Export power density distributions to HeatWave for thermal analysis.
Aether is a unified, finite-element package for calculating electromagnetic fields in three-dimensional structures. The program employs the FETD (finite-element time-domain) methodfor fast solutions. Aether covers the full range of RF and microwave applications. The code isoptimized for personal computers with efficient memory utilization and high speed. A typicalmodern machine can represent meshes with millions of elements and accomplish solutions inminutes.
