A SMALL DOUBT ON PORT POWER VALUE !
Hi all, I am new to this software and I am trying to simulate a multi-layer structure on which plane electromagnetic wave is allowed to fall at normal incidence. I kept the port power at the default...

Hi All, I'm wondering if there is a possibility to mimic a surface wave propagating by using a very thin waveguide structure rather than utilizing surface plasmons. For example, can we use a thin...
View ArticleHow to add a condition on the mode solver when using the parametric sweep?
Hi, I am using the RF module of COMSOL 4.3b to determine the effective refractive index of the modes of a waveguide as a function of the wavelength (for instance between 600 and 700 nm). I am therefore...
