The lossless part can be described in three ways
: B& E# K: x2 i$ M* \) W( |! Z' Y 0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency
9 q7 d$ q( B1 d! y% {% @, ]( \ Capacitance C' in [uF/m] if Copt=0 or in [uMho/m] if Copt=power frequency
9 C1 Z8 C4 x0 y9 r: S3 z9 `4 u 1. Modal surge impedance in [ohms]; Z=sqrt(L'/C')
3 V; W9 ~) x p0 E0 p Modal propagation velocity in [m/s]; v=1/sqrt(L'*C')
& ]. r' G8 ~3 Y3 n3 C$ Y0 y! G 2. Modal surge impedance in [ohms]

The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)
- A- A4 Y6 e% S& @8 }" L# w length= length of line in [m]
8 N0 v2 {% l" y6 Q8 y: D帮助里面的,说的够清楚了吧( r% _3 p- Y* S: h% E
Xopt在setting里面设置,如果用的是atpdraw的话 |
