for
metallic conductor of planes, a is the separation, b is the width of strip
taken in y direction and
η
is the characteristic impedance. In deriving
these relations it is assumed that losses have negligible effect on eld dis-
tribution. Substitution of values of parameters, involved in expressions of
α
, leads to the curves of Figure 2.25. These curves lead to the following
conclusions.
