Capacitance is concept of lumped circuit. when the frequency increase, the "inductance" appear , So the " capacitance" you see also change At 2015-01-07 15:03:39, "\"icer world\" <dmarc-noreply@xxxxxxxxxxxxx> (Redacted sender \"icermail@xxxxxxxxx\" for" <DMARC)> wrote: >Hi Experts, >Happy new year! >When I extract the RLCG of ideal transmission line, I observe that the >capacitance varies in different frequency, although it's small.
