Title:
METASURFACE DEVICE, METHOD FOR PREPARING SAME, AND MAGNETIC RESONANCE IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/078101
Kind Code:
A1
Abstract:
A metasurface device for a magnetic resonance imaging system, a method for preparing the same, and a magnetic resonance imaging system. The metasurface device comprises: a printed circuit board (100), comprising a dielectric plate (110) and a first electrode (120) and a second electrode (130) respectively disposed at the front and the back of the dielectric plate (110), wherein the first electrode (120) extends in a first direction, the second electrode (130) extends in a second direction perpendicular to the first direction, and orthographic projections of the second electrode (130) on the dielectric plate (110) are located at two ends of an orthographic projection of the first electrode (120) on the dielectric plate (110), so as to form a parallel-plate capacitor; and a variable capacitor (200) connected in parallel with the parallel-plate capacitor.
