The obtained optimal polarization state to maximize the power absorption to the LHD plasma is compared with the ray-tracing code that includes mode content analyses, which indicates that the calculated results are generally in good agreement with the experimental results. The analyses show that optimal coupling to plasma waves requires a fine adjustment for an incident wave polarization even for perpendicular injection due to the finite density profile and the magnetic shear at the peripheral region.}, title = {Optimization of Incident EC Wave Polarization in Real-Time Polarization Scan Experiments on LHD}, volume = {11}, year = {2016} }
