Nov 18, 2024 · Hello, I am trying to plot the electric field of a nanowire using COMSOL 5.3a RF module. I have been exploring emw.normE, emw.Ex (Ey,Ez) etc, but I am wondering how to just plot E⇀ …

Jun 11, 2024 · My question is, is the average obtained from the frequency domain study equivalent to a time-averaged surface average normE in the time-dependent study over several periods?

This article (includes demo videos) shows how to set up an optical scattering model of a gold nanosphere in COMSOL Multiphysics®.

Dec 31, 2013 · This post explores how to make 3D plots of vector fields using the 2D axisymmetric formulation in the RF Module or Wave Optics Module.

Jul 5, 2022 · Mode analysis is an essential tool in radiofrequency and wave optics calculations. Learn how to carry out this type of study here.

Jan 8, 2018 · The following results show the envelope function and the norm of , ewbe.normE, which is equal to . Here, we can see that we get the correct envelope function if we give the exact phase …

Aug 16, 2024 · Hi, I am using the scattering field formulation for my model. I am using an x-polarized negative z-propagated plane wave as my background electric field. My structure is a box consisting …

Finally, Figure 5 shows a comparison similar to that in Figure 4, but here the plots show the expressions 20*log10(<tag>.normE) (<tag> is the physics interface tag – ewbe and ewfd, respectively).
