Please forgive me for a stupid question... where I can get a copy of one of these softwares for free ??? I am just a ham radio amateur and try to design few microstrip filters for my microwave equipment...
I already post another thread, maybe someone will help me
If anyone has a FTP I will apreciate very very much...
for me i always say cst is best for 3d geometry that is more friendly and simple to teach it,ansoft designer prefectly for ebg,pbg,metamaterials,HIMS,hfss faster than cst but huge memory,xfdtd is the most accurate with cst but so slowly than cst
