Abstract-The high-frequency method for solving the scattering from homogeneous dielectric objects with electrically large size in half space is presented in this paper. In order to consider the scattering fields of the targets in half space, the half-space physical optics method is deduced by introducing the half-space Green's function into the conventional physical optics method (PO). Combined with the graphical-electromagnetic computing method to read the geometry information of all visible facets, the equivalent currents and the reflection coefficients are utilized to account of the homogenous dielectric objects with half-space physical optics method in half space. The numerical results show that this method is efficient and accurate.

“…In addition, several numerical experiments conducted, as part of this work, using commercial software, have shown that the maximum difference in SAR between our 3-layered planar model and a corresponding 3-layered spherical model does not exceed 10%. However, the use of a planar model simplifies formulations and allows for the implementation of the accurate and computationally efficient CIT [26][27][28][29][30][31][32].…”

“…The resultant complex images are only a few images with complex amplitudes and complex locations. While the CIT is applied in this paper to solve a three-layer model of the human head, it can be easily extended to other head models consisting of any number of planar layers with different types of conductor or slot antennas [26][27][28][29][30][31][32].…”

Abstract-This paper uses the accurate and computationally efficient complex image technique (CIT) to find the electric field and SAR distributions inside a human head illuminated by a finite-length dipole. The human head model used consists of 3 planar layers of lossy dielectrics. The accuracy of the results is verified by comparison with HFSS software. It was found that the CIT requires about 1 minute and 16 MB of RAM, while HFSS requires about 2 hours and 1.5 GB of RAM to find the SAR distribution using a 2.19 GHz Core 2 Due PC. The CIT method can also efficiently solve other types of antennas on other planar head models.

Abstract-In this paper a new technique for the evaluation of the Green's functions of filament sources in layered media, is presented. The technique is based on the annihilation of the asymptotic and singular behaviors of a spectral Green's function. The remaining function, after annihilation, is treated using a two levels discrete complex image method (DCIM). The application of the proposed technique, provides a complete analytical expression for the spatial Green's function, in terms of the iterative value of the propagation constant. This expression consists of the annihilating functions and a number of complex images. In order to validate the proposed technique, microstrip lines and slotlines are analyzed and the obtained results are found to agree very well with those obtained using a commercial software.
