摘要：
A phantom device (10) for reproducing at least one electromagnetic (EM) characteristic of a reference object made of an electromagnetic lossy medium, in particular a biological tissue, when illuminated by an EM wave with a predetermined frequency f1 emitted by an EM source (2), said phantom device comprising at least one unit structure, said unit structure comprising:
- at least one first dielectric layer (12) comprising an upper surface (13) face to the electromagnetic source (2) and a bottom surface (14) opposite to the upper surface (13),
- said upper surface (13) being at least partly transparent to the electromagnetic waves emitted by the source (2);
- said bottom surface (14) being at least partly reflecting for the electromagnetic waves transmitted through the first dielectric layer (12);
- said at least one first dielectric layer (12) characterized by a complex dielectric permittivity of its bulk material ε 1 ∗ =ε 1 ′ − jε 1 " having an absolute value in a range between 3 and 40;
- said at least one first dielectric layer (12) further characterized by a thickness T 1 at least equal to 1/4 of the wavelength of the EM wave in the medium of the first dielectric layer (12).
