Hi I am working on srr metamaterial absorbers. I want to vary the angle of incidence of the plane wave which is now normal by default. Can anyone help me with how to do it?
Hi mamase, Oblique incidence means that the waveguide is not being fed by another similar waveguide, which means it must be fed by a different waveguide supporting different modes, such as free space. You can set up a free space oblique excitation by Assign Excitation -> Incident wave -> plane (...)
Hello, I want to model a periodic unit cell in HFSS with a plane wave excitation in the XZ plane with varying angles of incidence. I have started by modeling an air box (20mm x 20mm x 187mm) with PML boundaries on the +/- z sides of the box and Master/Slave boundaries on the other sides. For the top and bottom faces (...)
how to set plane wave incident angle in CST Microwave studio
A search of the threads in this forum shows that, in far-field analysis at least RHCP and LHCP can be shown from antenna structures. This is not actually very useful if one is needing to use a microwave port to excite a circular polarized wave into a device model, such as a polarizer, or square waveguide. The plane (...)
In plane wave elliptical polarization, the book said if the Ellipticity angle is possitive, it is a Left Hand Circular polarization(LHC). If Ellipticity angle is negative, it is Right Hand Circular polarization(RHC). My question is how can Ellipticity angle be negative? en.wi
Hi, I am trying to design a microstrip reflectarray fed with a offset horn antenna. And I have some questions. 1) Unit cell and phase curve How can I model a unit cell in HFSS such that all the information can be included? For example, the incident wave is close to but not exactly a plane wave and thus the incident (...)
Hi, I am using HFSS for the Unitcell, I wants to find S21 as function of frequency for different incident angles in floquet port. please anyone could suggest me how to change the incident angle of plane wave in floquet port.
Hey can anyone plz guide me how to define incident angle of incident plane wave in hfss..i need to plot bistatic radar cross section for a particular incident angle but i am not getting how to do it in hfss..
with planewave it must be done post processing - the simulation is much longer Added after 1 hours 29 minutes: in attached file you will find an example of scaning for anisotropic medium
Hi in CST MW. I have a plane wave impinging over an antenna with discrte port. The output at the antenna port is a F parametr called normalized spectrum. The angle of incedance of the plane wave varies in parameter sweep and I want to get the F parameter at the antenna port. It works for a single run (...)
For a finite size you can use plane wave excitation but you will have to calculate the reflected power using field calculator yourself.
I'm stuck and need a little help here... When calculating the reflection coefficient of a parallel-polarized plane wave obliquely incident on a dielectric boundary a point of zero reflection occurs at the Brewster calculating the tranmsmission coefficient r
Dear all, The code in Sullivan's book is for total/scattered field formulation for a plane wave aligned with the grid. My question is: how do I create a plane wave which is not aligned with the grid? Can the incident array still be used? How? Any sample code (for 2D case)? Or at least a pseudocode.. Please help. (...)
Hi all, I have a doubt related to the angle of incidence in infinite arrays (FSS). In the excitations -> incidente plane wave, I can change the theta and phi angles. I implemented a Jerusalem cross by a tutorial which I found on Internet and in this tutorial the author select phi=90? and theta=45? as a scan (...)
Hi, On the plane wave excitation dialog box you can define the propogation normal. Just translate the angle of incidence to unit vectors and set it there. I think that is what you need, doesn't it ? P.
all EM wave are composed by E and H vectors; on the plane orthogonal to the propagation direction, E and H are orthogonal the one respect the other one. Since H is always 90 far from E, we may concentrate our attention to the E only. With respect the horizons, E may assume any starting angle, and when EM propagate that (...)
I want to design a FSS with big attenuation at 140GHz and 90-130GHz is ts passband .I want to use metal on the substrate.I will simulate with normal incident plane wave and plane wave with incident angle separately, and see the stability of angle of incidence of the FSS. Now I wonder (...)
