      Complex imaginary number math is the routine way to analyze the SWR of complex loads and can be done if you have access to a calculator or computer program that will handle it. Even so, the math gets tedious in a hurry. Fortunately, there’s a very easy way to analyze complex loads using graphical methods and it’s called the Smith Chart. See
