An Efficient Full-Wave Electromagnetic Analysis for Capacitive Body-Coupled Communication

Figure 4

Variation in propagation loss among three human arm models: skin-only-cylinder (Sk-Cyl), skin-only-rectangle (Sk-Rec), and standard four-layer-stratified (Str4) for distances 20 cm, 40 cm, and 90 cm with (a) vertical couplers [6 × 6 × 3], (b) horizontal couplers [5 × 2 × 1]; all coloured symbols show variations with boundary conditions, mesh sizes, dielectric properties, and dielectric layer thicknesses for Str4 human arm model with 40 cm distance.
