Evaluation of effect of wall on wave propagation at 300 GHz

To evaluate wave propagation at 300 GHz using a simulator, we constructed an accurate measurement system for wave propagation. In this study, we used simple propagation models and evaluated the system by comparing the results of simulation with those of measurement. From the results, measurement using the system had the same accuracy as measurement in free-space. Then, we added a wall and compared the results of simulation and measurement. The difference was within 1.5 dB at 300 GHz; thus, we concluded that our system can measure wave propagation accurately and that evaluation using the simulator was valid. Finally, we measured actual data dispersions by measuring some wall materials using our system.
