## how can i change the angle (theta and phi) of incident wave in waveguide in HFSS?

Hi, everyone I am now using HFSS version 13 to calculate S11 and S21 of a metamaterial absorber. wave ports and PEC/PMC B.C. are set up in the simulation. For the wave port, the plane wave incident angle is zero in default, but I want to use an oblique incidence(for example theta or phi=10 deg). What should I do to realize oblique incidence? Th

## Help-HFSS simulation with Master/Slave Boundary

If the wave is at normal incidence, there is no phase difference between your boundaries. That only happens when the wave is at some oblique angle of incidence. In this regard, normal incidence is extremely easy with HFSS. Hope this helps!

## What is Halo Implant Shadowing?

Ion implantation is probabilistic, in where the ions end up, and "hard mask" features are able to affect this too. Halo implants tend to be shot at oblique angles from normal so they can "reach under" spacer. If gates are too tightly packed, it becomes sort of like getting sunshine on the sidewalk, downtown - some places are better than others, de

## Oblique stripes on high current traces

Hi guys, I opened my microwave oven and found on one of the PCB's stripes on some traces. The stripes are present on traces with mains voltage. Any ideas why they are there? Thanks in advance.

## How to simulate EBG reflection phase with different incident angle in hfss

Dear all, I want to get reflection phase plot in oblique incident. I know maybe I can use Master/Slave boundary condition instead of PEC/PMC, could anyone give me some detail simulated steps ? Appreciate your help !!

## Oblique part orientation: OK with machine placement?

Hi, For more compact component placement, sometimes I find it might be better to align components, especially small resistors and capacitors, in an oblique orientation, say, 45°. Especially when there are many small bypass capacitors in the fan-out, I find this arrangement could save space many cases. Would this cause probl

## Please recommend a Tilt sensing device

Hi, I would like to ask a question on Tilt angle sensing. If there is an application which requires the device to be on the upright position, and should generate an error whenever there is an oblique angle between device?s top direction and the upright direction, what sensor should be used to detect it? I read some arti

## Need to oblique incident fdtd code

hello I am desperately looking for a 2D FDTD code with an oblique plane incident wave! I have read many books but have difficulty implementing them so need a code to help! PLz! 8-O

Dear All, I am trying to analyze the A-sandwich radome in HFSS. Please find the attachment for hfss model for the A-sandwich radome. I am getting the expected results for normal incidence only, but not with oblique incidence. It is required to find the insertion loss (also in terms of transmission coefficient) of the radome with the variation

## Floquet Modes CST MS Explain

waveguide use when u want to simulate normal incident floquet used for general any oblique angle floquet mode only operate with unit cell as it simulate ur design as periodic structure

## Simulate the oblique incidence at both te and tm polarizations---help!

Hi every body, Now I am focusing on the simulation for the refletion phase of the EBG structures, especially, i want to plot the reflection diagram for the oblique at both TE and TM polarizations as the attached-picture below. However, I don't know how to do it. Can anyone help me? Thank you for much! I hope early receive your reply. [url=ht

## How to get Current along the vias in mushroom struct. HFSS??

Hello everyone, I am trying to find the current(Amps) along the vias in the seivenpiper structure using HFSS 10. Structure: I am simulating a unit cell with patch on a grounded dielectric slab which is connected to ground by vias. The excitation I am using is plane wave with oblique incidence and TM polarization. For TM polarization obliqu

## oblique incidence in FDTD

hi i am writing a code for FDTD technique.i need to have an oblique plane wave.i have read taflove 's book on FDTD. But 1)i would not understand the look up table method for incident wave.There are some equations regarding the geometrical interpretation of the method.What is the meaning of it.Should i use those equations in my code 2)To

## How to make oblique planewave in FDTD?

u can implement an oblique incident wave by multiplying the field you would use for a normal incident wave with a phase term. the phase term is a function of position. for example, lets assume you excite an incident wave in a 2D simulation by forcing the E field at y=y0: Ez(x,y0)=Ez(t). this is a plane wave traveling in the y directions. if you

## CST example with floquet mode

hi all,many here face problem of changing the oblique angle so i upload cst example file i hope help all enjoy

## on reflection phase of periodic structures in HFSS

try using floquet mode that able u changing the oblique angle in that site u will find floquet mode in hfss

## help simulate EBG structure with periodic boundary in CST

hi,if u confuse with that method that i already test it with (CST and HFSS) give good comparison that method has limited to only normal incident,so if u like check any oblique angle,sorry u that method not work well so i suggest u use floquet mode that allow ur changing the angle of incident ,in CST in frequency solver in HFSS ,it already suppor

## How to simulate a patch fss using HFSS?

thank you for your reply,but I am looking for frequency selective surface(patch) simulations in hfss for oblique incidences of plane wave.

can anyone help me how to simulate fss in hfss for oblique incidences for tm(E-vector in the plane of k vector) case.

## oblique incidence S parameters in case of reflect array

Hi,on HFSS I'm simulating an oblique incidence(with a plane wave) to infinite reflect array and i would like to extract S parameters (reflection coefficient).Any idea?? I am also doing some try on field calcullator but i am unable to get results.....thanks in advance......... Farooq:cry:
