(a) Schematic representation of the polymer membrane textile under human body radiation from the skin where (I), (R) and (T) represent respectively the incident, reflection and transmission coefficients of the electromagnetic waves. (b) Elementary unit cell used for the FE calculations with perfect matching layers (PML) and periodic boundary conditions (PBC). (c) 3D and in-plane view of the polymer membrane of thickness h, drilled with a triangular array of air holes with period P and diameter D.
