RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

EM Simulation fundamental - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

Hi all :
like to seek your advice regarding fundamental EM simulation, for 4-6GHz
frequency range. It is my first time doing EM simulation. I'm using
SonnetLite software tools.
I'm not sure about the fundamental
of this EM simulation, like what is the main purpose. I learnt about
EM before, about far-field, Common mode, differential mode radiation.
But I'm not sure how to relate to simulation purposes.
any kind souls out there enlighten me?
Thanks so much.
appreciate if anyone can share simple notes to explain this EM simulation

EM simulations is used in order to simulate
physical phenomenon related to high-frequencies: Skin effect, reflections
from enclosures, coupling between transmission lines. In EM simulations
you take into consideration both physical and electrical properties
of distributed elements and get an overall picture of the performance
besides the linear simulation and gives the designer an insight about
the performance of the circuit in real environment - like inside an
enclosure or shielded cans. It is also being used to find problems in
high-frequency PCB layout: radiation from vias, interferences etc, it
is used to simulate Antenna performances...
There is plenty of
material available in the Internet over EM simulations.
