Silver faces and material assignment crisis

Hello, I am struggling with a simple modulator 3D structure. I tried to create the geometry in many different ways but the cleanup wizard always appears to bother me. I tried to extrude a 2D surface, or directly create the 3D blocks, but I always encounter problems such as silver faces, and I experience a constant struggle with material assignment (many boundaries are not correctly assigned). I had a 2D model with the identical structure, and never encountered these kind of problems. WIth the 3D, it is a mess. Please help me understand how to cope with this. I want to compute the S parameters and characteristic impedance. I've also tried to insert some boundary conditions such as impedance boundary condition but I am not even able to select the correct faces! This model is simple, there is nothing sketchy about it. Please help me. Thank you
