Dear all,
I have a question concerning dielectric and how to model correctly
printed stripe (fritted glass) on a surface of dielectric material.
According to the reference manual, " Ordinary dielectrics are surrounded by a vacuum". But in my case, the transition between the dielectric and the print color is different to the transition from dielectric to vacuum. And since I'll have the printed stripes on different layers, the difference is significant.
My purpose is to simulate with Radiance a laminated glass with fritted
stripes on the surface in-between the two laminated glass sheets. I want to check the view to the outside and the transmission of such fritted glass.
I already modeled the stripe as a plastic surface with a very small gap
between the two panes of glass. But I obtained wrong result because of the air gap between the stripe and the dielectric (glass) panes.
Any idea how to model this correctly?
What happens, if the dielectric is not completely "boxed", but parts of the "box" replaced by plastic material?
Thanks in advance

Hi Francesco,
Your posting arrived twice -- were you not sure that it was posted the first time? You can always double-check at radiance-online, since the archives are always current.
The "interface" type is what you are looking for, I believe, since it allows you to specify the dielectric constant on either side of a boundary. Modeling materials at this level of detail requires that you know very precise things about the geometry and physical properties.
It is OK to have some sides of a dielectric capped by an opaque material, such as plastic. If you have no cap, just an opening, then the results will not be correct.
Best,
-Greg
