Abnormal absorption and scattering effect of human ear model for electromagnetic waves

To explore the effect of human ear outline structure for electromagnetic waves, two human ear‘s models, a big one (model 1) and a small one (model 2), were made in proportion as real human ears (Fig. 1). The installation picture is shown in Fig. 2, and its geometry structure and size are shown in Figs. 3 and 4, respectively.
