Dear volker,
Thank you very much for your kindly reply.
But how to 'find' the addition EM coupling between the pieces? Can I add more Floquet modes in HFSS simulation? I can simulate with multiple modes excited in Floquet port and the S parameters of multiple modes are calculated, but how to...
Dear all,
I attached 3 models RX_J4RX.hfss, RXRX_J4.hfss and RXRX_J4RX.hfss about multiple-layer structure simulated by HFSS. I need to calculate the S parameters of these models.
The third model RXRX_J4RX.hfss, is exactly the combining of models RX_J4RX.hfss and RXRX_J4.hfss, therefore, the...
Dear all,
I need to calculate the reflective effectiveness of multiple-layer structure. The Floquet ports are set and then the S parameters are calculated. The S11 can be acted as the reflective effectiveness. If there is only one mode excited in Floquet ports, the S parameters are 2*2 matrix...
Dear 123jack,
Thank you very much for your kindly reply.
I tried the sobel edge detection by matlab but don't know how to get the region I am interested. The results by edge detection are some small non-connected segments.
As my know, the common features of all pictures provided to me are:
1)...
Hi 123jack,
Thanks for your kindly reply.
Not just for purple pixels. The goal is to check whether there is an approximate width line at left side inside the ellipse. Color of lines could be different according to different experiments.
Another problem is that there could be some distrubs to...
Hi SunnySkyguy,
Thank you very much for your kindly reply.
for 1), I think it's the problem to improve the picture quality from hardware and it is not decided by me:(
Could you please give me more details on how to convert from raster to vector by math program?
Thanks,
Tang Laoya
Hi tpetar,
Thank you very much for your kindly reply.
The lines are not always on the same place. The size of ellipse area could also be different.
Currently I have only these two pictures for comparison, maybe I can get more pictures, but the are similar.
Thanks,
Tang Laoya
Hi cherryman,
Thank you very much for your kindly reply. It's the jpg format. Now the problem is that we require to check the left line even when the signal is small and the image quality is poor. For the 1.jpg, when I use edge funciton of matlab only the right line left.
Now my first problem...
Dear all,
I need to detect two lines in the picture but the left line can't be checked by eyes sometimes. I attached two pictures, 1.jpg is the one that the left line can't be checked by eyes, and we can check the left line in 2.jpg.
I have two questions:
1) the interested part is inside the...
Dear all,
I am trying to solve this kind of problem: a multiple-layer absorbers which contains several layers of FSSs sandwitched by parallel absorbers. This problem can be solved by HFSS directly. Howerver it is slow and I would like to solve it by transmission matrix method. This method needs...
Dear all,
Is there any people research on the electromagnetic simulation by meshless or meshfree method? I am trying to study this method, could anyone discuss the advantages of this method, comparing to the traditional methods (FEM, MOM, BEM, FDTD, and so on), the classical articles and books...
Dear all,
I need to simulate the induced voltage in received coils by transmitted coil. I have successfully do it by eddy current model, the method is to set 1 A current on the transmit coil and then calculate the impedance matrix of coils, as a result, the elements of matrix is just the...
