Abstract :
Upper and lower bounds on the line inductances are presented for the first time for planar transmission lines with anisotropic magnetic media. Green´s functions are derived for the general structure by using recurrent relations. Numerical examples involving striplines and coplanar waveguide are presented, and the calculated values of the quasi-static characteristics of stripline on an anisotropic magnetic substrate with the tensor permeability are in good agreement with measured values
