How can I control/choose my grid size Dx, Dy, and Dz?
Dx,Dy, and Dz values’ depend on the simulated structure and they can be changed manually by the user, but they have to be set smaller than a certain value that depends on your substrate dielectric constant (epr), your mesh density “chosen between 20 or 10 cell per wavelength”, and the maximum frequency the structure is simulated for. Tip: please note the “Max” value on top of boxes to set Dx, Dy, and Dz on the left hand side of the EM-Core/EM-Supreme main program window. This “Max” is a cap on Dx, Dy, and Dz that cannot be exceeded and is a function of relative permittivity epr, your mesh density, and the maximum frequency your structure is simulated for. All of which can be changed using the “Settings Window” under “Options” in the main tool bar. (Tip: faster simulations Dx, Dy, and Dz may be set as close as possible to MAX, which can be achieved by changing the frequency range in the Options-Settings window).
