Fig. 3.2 Frequency response of a two-layered composite structure with the bottom layer oriented
at 0 and 90 ◦ with respect to the top layer. The principal-axis conductivities of the two layers are
[2 × 10 4 , 100, 100] S/m, which is typical of cfrp composites. The x-axis is aligned with the fibers,
and the y- and z-axes are transverse to this direction. There is enough fiber-to-fiber contact in the
transverse directions to yield a nonzero transverse conductivity
