Derivation of higher-order anisotropic impedance boundary conditions

在求解各向异性介质涂敷物体的电磁散射中 ,采用高阶各向异性阻抗边界条件可以简化求解过程 ,提高近似解的精度。文中采用谱域法导出各向异性介质涂敷平面的二阶张量阻抗边界条件 ,并通过例子证明其精确性。

A novel spectral domain approach was adopted to derive higher-order tensor impedance boundary conditions (HOTIBC) for anisotropic coated planar conductor. Second HOTIBC for cases of optical axis of anisotropic material in incident face and in interface between anisotropic material and air were given. The examples illustrate that the HOTIBC obtained coincides withs exact one perfectly.
