Abstract

AbstractAs an applicator for heating deep‐seated tumors in the human body in a non‐invasive manner, a multiapplicator system radiating TE wave is proposed. In addition, it is shown that a hot zone can be formed deeply inside the human body if a method for good adjustment of the amplitude and phase of each applicator element is used. As an actual example, a homogeneous two‐layered cylindrical human body model is used for the cross section of the adrenal‐kidney level. Numerical calculations are carried out for the case where several line sources are placed around this model. It is confirmed that a hot zone is formed near the center. It is also demonstrated that the FD‐TD method is effective for the analysis of the electromagnetic scattering of a TE wave by an inhomogeneous cylindrical model which is the most important in the algorithm in the present method.
