Abstract: Kobayashi potential method is applied to investigate the scattering behavior of a perfect electric conducting (PEC) strip buried below a lossy dispersive non-integer dimensional (NID) dielectric-magnetic slab. Dispersion characteristics are introduced through the Lorentz–Drude model. Due to dispersive nature of the medium occupying the slab, it operates as epsilon negative (ENG), double negative (DNG), mu negative (MNG), or double positive (DPS) material depending upon the operating frequency. Scattered fields have been obtained when the slab behaves as ENG/MNG/DNG or DPS. Efforts have also been made to highlight the impact of NID parameter and dispersion characteristics of the material of the slab. It has been observed that increase/decrease in the thickness of the slab decreases/increases the scattered field from the strip below the slab. Moreover, it also decreases as size of the obstacle increases. It has been noted that the effect of real part of constitutive parameters on scattering pattern is opposite to that of imaginary part of constitutive parameters for ENG, MNG and DPS slab while for DNG slab the trend remains same.
