The book by Ian Hunter is quite good:
Theory and Design of Microwave Filters
ISBN 0 85296 777 2
You may also have a look at the book by Cameron et al:
Microwave Filters for Communication Systems: Fundamentals, Design, and Applications
ISBN 978-0-471-45022-1
These books are quite new and have...
Use: Macros / File / Make Archive
And if you don't want to backup the files from MWS, just use the macro once and you will see which files that are critical.
No aw, I'm not fully sure. I've only tested mwStudio on a dual processor system.
But according to hxxp://www.cst.de/products/mws/technical/technical.htm :
Multi-processor support (parallel version for two processors on one main board, only for transient and eigenmode solver)
But next version...
dielectric constant for fr4
Government regulations (for example in the EU) will soon ban materials that are hazardous to people or environment, for example halogens like brominated resins used in FR4. Looks like one have to avoid FR4 in new low-cost RF designs.

75 50 ohm coax loss miss match
75 ohm was optimized for low loss in air-filled coaxial transmission lines, but not for power handling. 50 ohm was a compromise.
See the attached document for more info.
cst system clock has been set back error code 88
A quick search at Google:
https://www.google.com/search?q=flexlm+error+88
will tell you that System clock has been set back,
usually meaning that you somewhere on your system have a file dated in the future, so the license manager thinks you are...
I thought that Ni/Cu/Ag or Cu/Ag or Ni/Ag was most common.
What's the reason for using Si and Fe?
Update:
I maybe have misunderstood your post. How should I read Al-Si8Cu3Fe?
I'm talking of silverplating aluminium, and for example Ni/Cu/Ag are plated on the filter in that order. Ni is used...
I guess you are looking for linear phase filters.
Have a look in the manual for Filpro:

At the end of chapter 15 you will find a lot of good references:

helical resonator design
Have not seen any really good program for helical filter design, but I can recommend the book Filters With Helical and Folded Helical Resonators by Peter Vizmuller, Artech House, ISBN 0890062447.
Beware that a two-tone measurement cannot completely predict the output spectrum for wideband signals. It cannot for example replace an ACPR (Adjacent Channel Power Ratio) measurement, if ACPR is of any concern to you.
There was an interesting article in the May issue of MTT, titled Prediction...
