“…Using the aperture theorem, an aperture located on the infinite large plane is solved by Harrington and Mautz [1] in the beginning. Then, many other cases are studied [2][3][4][5][6][7][8]. The shape and depth of the aperture are the main concern.…”

The electromagnetic characteristic of the aperture located on a PEC (Perfect Electric Conductor) cavity is an important and challenging research in CEM (Computational Electromagnetics) and practical applications. Researches have been done well when the apertures located on a large flat surface. But the complex slots and apertures are still difficult to analyze, such as a thin long slot. The thin long slots present on different kinds of structures, such as missiles, aircrafts, handset equipments, and computers. In addition, most of the surfaces are non-flat. Furthermore, the multiscale characteristic of the structure makes the modeling very difficult in such cases. It becomes an increasing interesting research recently. A better result can be obtained by generating much more denser meshes. Because of the complexity of the algorithm and the ill-posed matrix problem, it is not an optimized option. In order to get a better use of the aperture theorem in the multiscale problems, a separation technique is developed in this paper. By using the readjustment of the equivalent electric and magnetic currents, a simplified model is proposed. Arbitrary shaped aperture can be very well handled through this method, especially the thin long slots.

“…In this paper, an exact full-wave formulation is developed for the rectangular groove problem based on the Generalized Network Theory and the equivalence principle [4]. This theory has been applied to a number of related aperture and slot problems in the past [5,6]. In particular, we will extend the work of Auckland and Harrington who applied this theory to treat the TE transmission through a slit in a thick conducting screen.…”

Electromagnetic scattering from a two-dimensional groove recessed in an arbitrarily thick conducting screen is studied. The groove may be empty or loaded with a lossy material which may or may not completely fill the cavity. For the partially loaded groove, the filling material is assumed electrically dense so that the standard impedance boundary condition is applicable at the top surface of the material. Employing a full-wave analysis, integral equations are derived for the tangential components of the electric field over the aperture. It is shown that the equations are identical for both partially loaded and completely loaded (or empty) cases provided that the aperture admittance of the groove is treated as the equivalent admittance of the internal medium looking into the aperture, thus simplifying the integral equations. When the groove is completely filled by a dense material, the formulation reduces to that corresponding to a direct application of the impedance boundary condition over the aperture.
