I'd 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.
Could any kind souls out there enlighten me?
I'll appreciate if anyone can share simple notes to
explain this EM simulation fundamental.

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.
