Hi,
Here a picture how to get to the "Read button":
Concerning the directory where the *.lay file ist stored, the default location should be at the project root. But by exporting the *.lay file you can choose any other location.
Hope it helped,
Cheers
Maybe it helps ...
"When the 8P8C connector was introduced, the pin-pair assignment maintained Pair 1 on the two middle Pins 4 and 5, and Pair 3 was split around Pair 1 onto Pins 3 and 6. The reason for the split pair was to maximize the mechanical compatibility of the connector with existing...
@volker_muehlhaus: You are definitely right, the MoM method is based on the asumption that the substrate is infinite and treats the example I showed above as infinite.
I am not a programer at Agilent and I just wanted to say that based on my experience, I get better results with the use of...
@volker_muehlhaus, i understood it was finite in X-Y. Please refer to the screenshot I attached. It is maybe more explicit than my previous explanation ...

Hi,
You can define finite microstrip/CPW substrate in Momentum. Just need to build the right stack-up with "open" boundaries at the top and bottom instead of "closed" at the bottom (in the Substrate Editor). You then have to use the appropriate ports instead of the default single-mode ones...
Hi Vigort,
I would do build the Substrate stack-up as depicted in the attached snapshots. I also attached an EMDS preview whcih should look close to the structure you want to have.
Regards,

it will be simulated according to the stack-up you build in the Layout Editor, with your "sandwich of substrates, metallization, vias, thin-film resistive layer, ... refering to the layers YOU mapped.
Go to the Layers Editor (Options -> Layers). There you can add/delete/rename any layers as you want.
(Note that you can also map any layers other than cond and cond2 as metal)
JB
in Momentum go to the Port Editor (Momentum -> Port Editor ...) and click on your ports. There you will see the impedance of your ports which is by default 50 Ohm.

You can use online calculators to find the right width, like this one for example: **broken link removed**
I would advise to use the AppCAD freeware from Agilent: AppCAD
you got it.
You set the background as PEC, then you simply design your vacuum rectangular cavity and apply electric boundaries in all directions.
It is by far more efficient (regarding time computation) to build your cavity like this rather than building a real metalic cavity box with the...
Hi ravi_litb,
varuniyengar is totally right when saying the thickness defines the operating frequency. Just to clarify a bit more (hope this is not redundant). When you go higher in frequencies you can see unwanted modes propagating through your substrate if too thick.
The choice of the...
