The table shows the following data:

- General case: gamma equals Propagation constant (gamma equals alpha plus j beta) equals the square root of (R-prime plus j omega L-prime) (G-prime plus j omega C-prime); Phase velocity u sub p equals omega over beta; Characteristic impedance, Z sub 0 equals the square root of (R-prime plus j omega L-prime) over (G-prime plus j omega C-prime)

- Lossless (R-prime equals G-prime equals 0): gamma, alpha equals 0, beta equals omega times the square root of epsilon sub r, over c; Phase velocity, u sub p equals c over the square root of epsilon sub r; Z sub 0 equals the square root of L-prime over C-prime

- Lossless coaxial: alpha equals 0, beta equals omega times the square root of epsilon sub r, over c; u sub p equals c over the square root of epsilon sub r; Z sub 0 equals (60 over the square root of epsilon sub r) natural logarithm of (b over a)

- Lossless two-wire: alpha equals 0, beta equals omega times the square root of epsilon sub r, over c; u sub p equals c over the square root of epsilon sub r; Z sub 0 equals 120 over the square root of epsilon sub r times natural logarithm of [(D over d) plus the square root of (D over d) squared minus 1]; Z sub 0 approximates to (120 over the square root of epsilon sub r) natural logarithm of (2 D over d) if D is greater than d

- Lossless parallel-plate: alpha equals 0, beta equals omega times the square root of epsilon sub r, over c; u sub p equals c over the square root of epsilon sub r; Z sub 0 equals (120 pi over the square root of epsilon sub r) (h over w).
