Hi, all,
I have set the boundary for the top and bottom free_space layers to open. Since I need to simulate the power transferring from one antenna to another in free space. I need a third "free_space" layer between my two antennas. Hence I defined three "free_space" (freeSpace_top, freeSpace_between and freeSpace_bottom) layers inside "Substrate layers" tab.
1) In "Layout layers" tab, I managed to set two "strip" and two "free_space" (freeSpace_top and freeSpace_bottom) in "layout layers". However, when I try to define the "free_space" between these two antenna, the "material" list only contain "conductor". It seems that momentum won't allow me to have the third "free_space" layers! Why is that so?? Should I use VIA in between istead of freespace??
2) Also, why does momentum ask for the material thickness for my "freeSpace_between" twice?? I need to input the information twice in both "substrate layer" and "layout layer" tabs. For "freeSpace_top" and "freeSpace_bottom" it disabled any settings in "layout layer" tab, but for "freeSpace_between", "strip_cond" and "strip_cond2", I need to input the material type, conductivity, thickness information, etc.
Thank you very much for explaining to me!!
