Hi, I am kind of new to COMSOL. I am working on impedance meta surfaces. My 2D geometry consists of two identical rectangles which share one common impedance boundary. I cannot figure out how do I have two objects which can have a shared impedance boundary which I will define using impedance boundary condition. What I have done so far is:
1) Create first rectangle with a line current as Union since the line current lies in the first rectangle.
2) Create second rectangle and used form assembly.
Help is much appreciated.

The impedance BC is for external boundaries only. For your application you should try the transition BC.

Cheers

Hi, Thank you for your reply. Can I use transition boundary condition as Impedance boundary condition? Because I need to use the equation which is specified in the impedance boundary condition. I am simulating negative refraction using impedance conjugating surfaces.
Here is my model file

I suggest you check the equations in the documentation and decide whether they are appropriate for your task.
