Using FDTD simulation, we revealed the higher-order modes and the polarization states of electromagnetic wave in the transmission system of ECH devices. The FDTD simulation code was developed to estimate the energy loss in the waveguide wall in this research project. We also clarify the occurrence of higher-order modes in miter bends and to clarify the polarization state in miter bend polarizers by our FDTD code.
Next, we simulated the optical response of the tungsten fuzz structure obtained as a byproduct of plasma wall interaction by our FDTD code. As a result, it was found that the absorption of electromagnetic waves is getting larger as the surface of tungsten becomes more rough.
