alt Hacker NewsGoing into the RF field myself, I've been troubled with the license costs of tools like HFSS and CST. After a brief test of the open source tool OpenEMS I've landed firmly on the newer open source tool EMerge (https://github.com/FennisRobert/EMerge). It's a little rough around the edges still as it was released in the fall. But I've already gotten good results from it designing my own RF hardware.
Apart from that I wonder how much of the resurgence can be traced back to more active conflicts around the world? There is a booming Drone and EW development within the military sector which could be what drives it?

not to mention the price of a remotely usable vector network analyzer will make any software look affordable
Tidy3d works very well (not free).
I gave up on OpenEMS.
Wow. Thank you.
Mil is driving a lot of small and large radar development, electronic warfare weapons, RF communications, etc.
Then you have a lot of work being done on new WiFi standards, satellie antennas, cell network development, and so on.
Also companies like Tarana are building a lot of unique things.
Oh interesting, I've heard of EMerge but haven't given it a try yet. Sounds like it's solid enough to be useful?
