Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

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.
