To export a quality animation, it is important to adjust the number of frames, frame rate, and resolution of your animation. In this video, we go over the basics of creating and exporting animations and discuss a few best practices. Whether you are showing your results in a presentation, on the web, or as a standalone video file, exporting animations will help you get your point across. I have simulated the Gaussian beam E field (at a single z value) on the x-y plane by placing the Gaussian beam equation under the Background electric field at the x direction.Showing visually engaging animations can be extremely valuable when conveying the results of your COMSOL Multiphysics ® model. Under the Electromagnetic waves, frequency domain. I am trying to make a 2D model of the electric field of a Gaussian beam at a given z value, such that the Gaussian beam's electric field appears to be a circular distribution on the x-y plane, and observe the electric field interaction between a gold nanoparticle with this electric field. For obtaining transmission spectra do I need to use port condition or what ? My target is to achieve Transmission spectra coming out from GaAs vs wavelength (say 800-1200nm). I had placed Point in GaAs and used that as Dipole source. My Goal is to get PL spectra ( Transmission ) vs wavelength. So In Parametric sweep now I can do Lambda dependent. In GaAs Material properties I had defined Relative permittivity as = GaAs_real(Lambda)-j*GaAs_imag(Lambda). I had used nm in Lambda since imported (ex. Previously in Parameters I had defined Lambda = 1000 and frequency = c_const/Lambda. I had converted n and k values to Relative permitivity say GaAs_real and GaAs_imag. I had imported Refractive index values via interpolation. ![]() I had attached the concept of my simulation as picture where you can understand my idea.įor obtaining Wavelength vs Transmission spectra I need to include all Refractive index (n and K values of GaAs). ![]() Wave Optics Module: Electromagnetic Waves, Transient (ewt) Perhaps Matlab? I have no problem extracting the data from Comsol and then subtracting the results, but I am not sure how to convert the result into data Comsol can use for functions like mphplot. The other problem is that the parametric data set does not encompass the domain point probe, so I would not be able to FFT the data sets unless I store every single time step taken by the solver. The issue is that Comsol will only join data sets at one time step, so I would have to create a join data set for every time step. I have tried to define a parametric sweep over d33 with two values (0 and 1e-17). It would be great if I could also subtract the results of the domain point probe that is defined in Comsol's model (in order to FFT the transient data at that point). Then I would like to subtract the results for Ez. I would like to extend the second harmonic generation tutorial offered by Comsol ( I want to run two simulations: one with d33 = 1e-17 and another with d33 = 0. I would be thankful if anybody share his/her experience on this. Right now, I am moving only scatterer, and I am not getting microscopy profiles as I want. If it has to be at center of enclosed boundary, I am thinking to move enclosed boundary also with scatterer such that scatterer is always center to closed boundary. In my case, scatterer moves, similar to scanning microscopy. Does Scatterer has to be at center of far-field closed boundary always for correct results?. ![]() Can I know any improvements is comsol 4.4 version on this far-field limitations in comsol? or I have to go my own modification in far-field calculations?Ĭ.uk/download/pdf/99111.pdfĤ. He also explained boundary shadowing problem, if far-field domain does not have radiation source and scatterer. (Please see appendix section, if you have time). ![]() He implemented far-field calculation with COMSOL 3.4 in material medium with a little modification with Matlab code. I have read the thesis in following link for for field calculation. If I defined a part of circle with scatterer at its center in free space (in 2D) and integrate this boundary to incorporate collection lens effect of a particular NA, Can I expect correct results?ģ. (If I read about scatton-chu formula, a closed boundary is defined for antenna field calculation). Even in free space medium, Do I have to define full enclosed boundary to calculate the far-field?. Does not it work for other homogeneous material medium, for example Glass?Ģ. If I study 4.4 waveoptics module user guide, it says, "far-field is calculated in free-space". I would like to know a few clarifications about COMSOL far-filed calculation in Wave Optics module.ġ.
