Hello All,
I was wondering if someone might be able to help me determine the fringing capacitance due to a parallel plate with an extended dielectric?
My test project (attached below) is just a simple two parallel plate setup with a Lumped Port connecting the two at the center of the two square plates. I set the resistance to 1ohm and the reactance to 0ohm.
If I use the -1/(2*pi*freq*im(Z)) output, the capacitance is an averaged capacitance across the entire plate, right?
If I use that Q = CV, I would think that I can integrate along the Efield path to determine the Voltage, but I'm not sure how to measure the charge on the plate.
I guess as a follow-up question, how does the modal solution set-up the driving field for a Lumped Port? Is it somehow normalized or is the input field strength variable depending on the dielectric separating a parallel plate?
Thanks for any help you can provide!
