Re: phd suggestion
I don't think RFMEMS is a surely good research topic now.
The best time for RFMEMS research has already past, and the future is in doubt.
I say this as you can find that it is no longer easy to invent new RF-MEMS device ideas, simply because a lot of work has already been done.
Maybe the application of such device in filters, antennas is still active, you'll find the process used to achieve those goals are complicated.
What about the industry of RFMEMS? Like other MEMS , no one can accept its complexity in manufacture and relliablity issues. Successful models are only some kind of swithes or FBAR in limited area.
I am interested in your opinion on RFMEMS topic. If anyone have some comments on this, I would be glad!
