I am a graduate student
in USA (born here as citizen, not visa) and want to know what simulators
are used by majority of engineers doing defense contractor work;
ie, L-Mart, Northrop, etc. I like Eagleware, but want to use what
I am likely to use when working in another two years. Any advice?

fact is there are a lot of software packages out there and learning
any one package does not guarantee that it will be used in your
future place of employment. Agilent's ADS seems to be the big name
in RF/microwave simulators.
However, other companies like
Eagleware, Applied Wave Research (Microwave Office), Aplac, et al,
make very good software and a lot of big name companies use them.
I personally don't like the ADS interface - never have liked any
of the EESOF/HP/Agilent software interfaces.
I'd say the
most improtant thing would be to build proficieny in simulations
in general, and the skills will migrate to any platform.
Well, that's my opinion.

For commercial / academic work I think
Agilent technologies' ADS is an excellent simulator. I have used
it to design circuits up to the 5 GHz.
The "design guides" facility
is an incredibly useful tool that speeds up the process. However
I would strongly advise anyone to understand throughly what the
engine does, whether you are doing steady state/transient/ harmonic
balance analysis etc.
The 2.5D EM simulator Momentum is really
good, based on integral equations that allow muti layer dielectric
problems to be reduced to simpler integral equations and solve by
using the method of moments.
I am simply in awe of Agilent Technologies'

Our company is currently using Microwave Office. In
the past, we've used the EESof packages (now owned by Agilent).
I've worked with EESof quite a bit and Microwave Office a little.
We also have Ansoft HFSS for EM simulation.
is to go with somehting that you think is straightforward to use,
but MAKE SURE that you understand how the simulator works. None
of them are perfect and each introduces modeling errors of some
type or another.
In summary, I'd say that for most simulation
tools, how you use it is more important than the actual choice of
software (assuming it works at all).

Welcome to forum!
are many RF & MW software design tools in the market. Eagleware,
Microwave Office, Agilent, Filtronic… etc are reliable and accurate
software design tools. They all can be competitor. It all depends
on design and applications. I strongly trust that defense contractor
companies will NOT disclosure what software design tools they use
to simulate their design. They can make their own version and for
different applications. This is due to national security issues.
Come on, that is a common sense! However, RF circuitry is RF circuitry,
electronics is electronics, physics is physics and intelligent one’s
can always come close or even a match “apples to apples” towards
any military hardware or software design and/or applications. If
I were you, I wouldn’t give too much concern about what type software
design tools defense contractor companies can use, but what will
benefit your career, dream and happiness in the future. That’s my
sole opinion. Good luck!

I used 3 types of RF simulators:
Microwave Office, Agilent-ADS and Eagleware.
The best performance
for Non-Linear applications is the ADS, with superb HB engine and
accurate models of Non-Linear devices. I used it to design Analog
PD linearizer for Power Amplifiers. It gave excellent results almost
the same as measured in the lab.
For EM simulations and linear
simulations the best is Microwave Office, because of its more convenient
user interface. I hope that Agilent will learn to make theirt use
interface a bit more friendly.

wow. Sonnet works with 6% error
for EM filters.
Microwave office has quite good interface, works
nicely. The EM part gives ill-fated results. Software is like food.
Good from home, bad from third party.

There are many recommendation
for Agilent ADS. Can I know if they is any ADS kit for download
which can be used.

i think the most used simulator is ADS , and MWO
but the ADS is the most powerfull as i think
i am using it
, and enjoying the use of it , and also i am using MWO , but i donot
