HFSS Conference 9th November 2005 Radiussing OMT, polariser, transition had radiussing of 60 µ at the corners Necessary to model this and adjust dimensions accordingly HFSS model of corrugated polariser Page 8 of 28
• Run as quarter model • Run twice HFSS Conference 9th November 2005 Polariser Model on HFSS V8.5 • Meshing started at 75,000 • Converged around 104,000 tetrahedra • Radiussing at 60 micron meant re-optimising dimensions • Runtime 90 minutes for convergence and 6 frequencies (2 Gbytes and 2 MHz) • Axial Ratio
