Model & assumptions
Z0 = 60 ln(D/d)/√εr. Rs = √(πfµ0/σ); αc = Rs(1/a + 1/b)/(4πZ0); αd = πf√εr tanδ/c. Loss = 8.686(αc + αd)length.
Low-loss TEM model with smooth, nonmagnetic conductors of equal conductivity. Excludes braid, connectors and mismatch. Skin depth must be small compared with conductor radius.
