Hi, all
As all know, in homogeneous strip line, the propagation speed  is the same
for both differential and common mode.

However, in inhomogeneous microstrip line, the propagation speed of
differential mode is faster than that of common mode.
In specific, the value of Cm/C is higher than Lm/L in inhomogeneous
microstrip line while the values are same in homogeneous strip line?

Could somebody let me know why it physically is?


Thanks in advance,
Jongbae Park.
