em boundary conditions

Hello,

I'm a little confused here.

So i know that setting your boundary to Electric is basically like putting a ground plane.

What is a magnetic boundary analogous to?

Also, i don't really understand why you would pick one boundary over the other in a particular simulation. Can someone help me out here?

Hi Rancid,
As you said electric boundary is analogus to Perfect Electric conductor (PEC). magnatic boundary condition is for Perfect Magnetic conductor (PMC). These conditions are useful in creating walls, also for waveguide port.

Regards
