In short, we can derive the input impedance that gets presented at the left-hand end of the line versus the line’s length for the upper schematic of Figure 2. It happens to turn out that using the ...

Input impedance of a transmission line, open at the far end. As we go to even higher and higher frequencies, the input impedance of the transmission line will oscillate between really high impedance ...

The Controlled Impedance Line Designer also includes a provision to determine the effect of manufacturing variation on input parameters, such as thickness on the output parameters (e.g., impedance).
