Schematic of reflection/transmission “wall” test setup. The E field is parallel to the composite surface.
The measured (“wall” technique) and simulated effective real permeability of the 4-ply UD CFRP laminate.
The HFSS unit-cell diagram of a 4-ply UD CFRP laminate from the (a) top and (b) side.
The measured (“wall” technique) effective real permeability of the 8-ply UD CFRP laminate. The angle is between fiber and E-field.
Schematic of waveguide test setup.
The measured effective real permeability according to the waveguide technique for the 4-ply laminate in (a) WR-90 and (b) WR-62, and the 8-ply laminate in (c) WR-90 and (d) WR-62 waveguides.
