A low-loss dielectric is one with a small loss tangent, that is, (o/we) <1. We can reduce (6.52) for this special case by applying a binomial series expansion to the value within the 6.3.1 Low-Loss Dielectrics interior square root portion of the equations. The expansion is n(n-1);- + (1 + x)" = 1 + nx + 2! and for x< 1 this can be approximated as (1 + x)" = 1+ nx So we have + 1+ (6.53) 08 Inserting...
