Hi,
I have calculated E **field** and stored **energy** in a cavity using **hfss** eigen mode. So maximum delta (resonant) frequency is used as convergence criteria in this mode. Now there is a question: How E **field** or stored **energy** can be used as convergence criteria in eigen mode?

The equation for SAR = (σ/2ρ) |E|? (W/kg)
Basically SAR is the amount of **energy** absorbed by a dielectric body mass.
There are bunch of solvers that simulate SAR. Could you shed some light on how they do it, meaning how do they calculate the density and mass of the object? How do they calculate the E **field**? Is it the S11 reflected

Hallo,
in fullwave simulation, waveguide ports are used to excite the structure with **energy**. I am talking about driven problems only.
A 2D Eigenmode solver determines the excitation **field** in preprocessing, and considers it as time varying boundary condition in the solution process.
The characteristic impendance and gamma are also known from th

Dear all,
it is the first time i use this site and i hope to find some help.
i have simulated a dielectric antenna with **hfss**.
Everything looks fine:
input impedance looks great (real part 50 ohm, imaginary part is zero at resonance).
S-parameters also look great 20dB return loss
the antenna is feed with a 50ohm coaxial cable.

Dear all,
When using eigenmode solver to simulate a resonator, I can get
a **field** distribution. I want to know, what is the **energy** storage of the
resonator regarding the simulated **field** distribution.
I want to know how much is the E **field** distributed when **energy** storage is given.
