Abstract
The report deals with the evaluation of the absorption characteristics of prolate spheriodal models of man and animals consisting of homogeneous biological tissues irradiated with plane waves at an arbitrary angle of incidence at and near the resonance frequency. Stevenson's series expansion method in the third approximation and the extended boundary condition method are presented in detail since they were found to be most amenable to the solution of the problem. A general formulation of Stevenson's method in the third approximation is presented which can be applied to an arbitrary angle of incidence and leads to an improvement in frquency range of validity and accuracy as compared with first order solutions. The report also deals in detail with the extended boundary condition method (EBCM), since it was found to be inplementable for realistic models at frequencies approaching resonance. Though the EBCM theory is well know, the application of the method has been stressed and certain improvements in the accuracy and efficiency of the computations are incorporated. Numerical results are presented and compared with known data published by others.
