Electromagnetic Simulation of Signal Distribution of Various RF Endoluminal Loop Geometries with Coil Orientation: Towards a Reconfigurable Design

Figure 2

Different simulated endoluminal loop geometries, defined within (a) a cuboid volume with dimensions of 5 mm × 5 mm × 47 mm, with four copper strip conductors (1 mm width, 47 mm length, and 35 µm thickness). (b) Diagonal single loop (DSL) based on two strips. (c) Rectangular double loop (RDL) based on four strips and thus four current path possibilities. (d) Diagonal double loop (DDL) based on four strips and thus four current path possibilities. It should be noted that the red and blue spheres represent positive and negative poles, respectively, of the capacitors and the excitation port.
