Fig. 1. (Color online) Measurement system of TEOIM. The microwave signal is generated by a signal generator, and then, it is amplified by a power amplifier to 30 dBm. The amplified signal is transmitted to open-ended waveguide through coaxial cables, and it is radiated to a sample from the waveguide. The optical indicator is monitored by a polarized light microscope system consist of a circular polarizer, linear polarizer, and the CCD camera.
