Hi there,

              I am working on the intellisuite software for the design of a
micromachined patch antenna where the silicon substrate is etched from the
bottom anisotropically..so that beneath the patch there is only air....now the
thing is if i try tio simulate this design in the EM simulator of the software
it divides the design into layers and then before simulation asks to feed in the
properties of each layer.....but i am ending up with both the silicon and air in
the same layer ...so does that mean that i can feed in the properties of only
silicon or  air in that layer .....i.e.if i feed in the properties of silicon
only will the EM module take those properties for the cavity of air too and vise
versa.So if this is so how do i simulate the design in the EM simulator. Any
advice will be of great help.

Regards

Piyush.
