Summary on Grant Application Form |
|
The PPP (Gradual Increase of Parameters) method is a computationally efficient, and very general, perturbation/iterative technique for numerical solution of electromagnetic field problems involving inhomogeneous dielectric bodies of arbitrary shape.The main tasks will be to (a) extend the method to a time domain solution; (b) to apply the existing frequency domain form to a range of new problems, notably interactions of human subjects with handsets in personal communications, for consideration of rf exposure hazards, proximity effect on impedance, and antenna pattern modification. Applications to medical microwave imaging and various antennas of part-dielectric construction will also be considered.The SIP (Spectral Incremental Propagation) method is a very fast approximate methods, based on plane wave expansions, which has so far been applied to scattering of an incidence plane wave by a perfectly conducting body in an arbitrary 2-dimensional geometry, with the electric field along the symmetry axis. It is proposed to develop, verify and apply extensions of this technique in which some of these restrictions are lifted. Results for both methods will be tested by comparison with exact spherical/cylindrical wave series solutions for simple geometries, and by experiment for complex bodies such as human subjects.
