A single short circuited transmission line is a distance d from the load and of length d.

Given a characteristic impedance of Z₀ and a load with complex impedance Z_L, this application will calculate the values of d and l.

• The real part of the impedance at the stub location must match the transmission line characteristic impedance
• The imaginary part of the impedance at the stub location must equal 0

This results in two equations that must be solved numerically using Maple’s fsolve function. Units are used throughout the calculation.
