Abstract(in English) In a previous study of a 2-D waveguide power transfer, a meander surface sheet could be used to supply power over a range of about 10 m. This paper shows a solenoidal conductor pattern as a more powerful wavelength-shortening method. An easy-to-laid 7 cm wide sheet sufficiently shortens the wavelength. And the size of the receiving coupler becomes the size of a business card. Simulates results show the propagation loss is -0.1038 dB/m, and the ratio of the coupler output to sheet supply power is 51.7 %.Assuming that the power through the end of the sheet is recovered, the efficiency is 93.6%.
