Numerical Electromagnetics For Personal Dosimetry Of Cellular Phones

The book "Numerical Electromagnetics For Personal Dosimetry Of Cellular Phones" offers a comprehensive examination of the hybridization of the Method of Moments (MoM) and the Finite-Difference Time-Domain (FDTD) method. This innovative hybrid approach enables the analysis of systems with multiple discrete regions by utilizing the principle of equivalent sources to activate their coupling surfaces. The work includes numerous examples that illustrate both the potentials and limitations of this method. Notably, it highlights the ability to accurately model complex and arbitrarily oriented mobile phone antennas, particularly typical helical antennas. This modeling occurs in proximity to a detailed voxel representation of the human head, which is crucial for safety and radiation pattern assessments. Additionally, a new technique is introduced to reduce power dissipation in tissues near mobile phones, leading to a novel design of a bifilar helical antenna. The book also addresses various personal communication devices used for satellite communication and radio base stations, demonstrating the strengths of the hybrid method in such applications.
