Presentation Transcript


1. Introduction to High Frequency Structure Simulator Pengcheng Jia

2. Background Introduced from 90s Simulation tool for complex 3 D geometries Using Finite Element Method Adaptive Mesh generation & refinement 2 Main Vendors—Agilent & Ansoft Merger from May 1 Transfer to Ansoft HFSS after Nov. 1, 2001

3. Requirement & Resources HFSS consume tremendous memory if fine result is needed 300M+ Memory and 400M+ processor is recommended Floating License Key within ECEWIN2K subnet Remote access to new Scully which has 1 G RAMBUS400 Memory and 1.7G P4 processor

4. Agilent HFSS

5. Ansoft HFSS

6. Features(1) Computes s-parameters and full-wave fields for arbitrarily-shaped 3D passive structures Powerful drawing capabilities to simplify design entry Field solving engine with accuracy-driven adaptive solutions Powerful post-processor for unprecedented insight into electrical performance

7. Features(2) Advanced materials Model Library-including spiral inductors Model half, quarter, or octet symmetry Calculate far-field patterns Wideband fast frequency sweep Create parameterized cross section models- 2D models

8. Applications Antennas Microwave transitions Waveguide components RF filters Three-dimensional discontinuities Passive circuit elements

9. Procedure to simulate Open or Make new project Draw objects Assign material property Define boundary conditions Solve Display result
