Figure 1. 1D lamination model with 2 symmetrical cases: net flux with symmetric b(z, t) and h(z, t) and odd j(z, t) (up) versus net current with symmetric j(z, t) and e(z, t) and odd b(z, t) (down)
Figure 3. Variation of induction throughout core with imperfect lateral insulation (component in phase with imposed current), obtained with fine mesh (blue dots) and with TD homogenization (in red, plus components b 0 , b 1 and b 2 in green, magenta and cy
