摘要：
In areas where snow has accumulated, it is necessary to consider the effect of snow on the wireless power transmission (WPT) system. This study focused on the variation in power flow through the WPT system due to thickness variation of ice and the dielectric constant of snow. A measurement system was created and power flow measured as S-parameters to study snow and ice influence. It was found that ice cover caused the WPT coils to detune, which when asymmetric caused high losses. However, completely filling the space between the coils with ice caused equal frequency shifts in both coils allowing the WPT system to operate at the shifted frequency.
