The theoretical design of a ceramic absorber as an EMI (electromagnetic interference) filter based on Debye's dielectric dispersion theory was carried out. Transmission-line loss due to the dielectric loss in addition to the short-circuiting effect is applied to the EMI filter. Conductive loss can also be applied to the EMI filter. The optimized design of the ceramic material, based on the idea of making full use of dielectric losses, is presented. Superior EMI-suppression effectiveness was verified under actual automotive vehicle installation testing. The flat-plate microstrip line structure yielded a product shape which is easily installed and integrated.
