    • A recording medium suitable for use in an impedance matching apparatus adapted to a waveguide transmitting a microwave to a load. The apparatus includes detecting diodes and a computer. The recording medium includes a program, which includes predetermined approximate expressions. The predetermined approximate expressions recorded in the program correspond to the detecting diodes. The program causes the computer to compute an approximation value of input power to the waveguide using the respective predetermined approximate expressions and output voltages of the detecting diodes. The program also causes the computer to compute coefficient of reflection and phase of the input power using the approximation value; determine whether impedances of the waveguide and the load match with each other based on the computed coefficient of reflection and phase of the input power; and execute automatic impedance matching of the impedance matching apparatus when the impedances of the waveguide and the load do not match with each other.
