Scattering of Electromagnetic Waves by a Coated Dielectric Spheroid

A Spheroidal Vector Wave Function Analysis of Field and Sar Distributions in a Dielectric Prolate Spheroidal Human Head Model - Abstract *

“…The EM waves scattered by a single spheroid or two spheroids have been well-investigated and some analytic solutions have been obtained to date [16][17][18][19]. There are, however, only few reports on the analysis of EM field distributions inside the human head based on the prolate spheroidal model, basically due to two difficulties in analyzing the EM fields inside and outside the spheroids.…”

“…In [21], translational addition theorems [32] were used in order to translate the wave functions in The matrix depends only on the scatterers; therefore, the scattered field for any direction of incidence can be obtained with the same transformation matrix. This method was used by some other researchers [22,[33][34][35][36][37] and had many applications in physics and engineering.…”

“…As mentioned in Chapter 2, the prolate and oblate spheroids are important canonical objects which can be used to model a variety of other shapes [14,15]. The problem of scattering of electromagnetic (EM) waves by spheroids with a confocal dielectric coating has been studied [36,37]. In [37] the scattering problem by a conducting spheroid coated with a confocal homogeneous dielectric layer is studied.…”

“…In [37] the scattering problem by a conducting spheroid coated with a confocal homogeneous dielectric layer is studied. In [36] the problem of scattering by a coated dielectric spheroid is solved.…”

Σκέδαση Επιπέδου Ακουστικού Ή Ηλεκτρομαγνητικού Κύματος Από Σφαιροειδές

“…Επίσης επιμήκη σφαιροειδή μπορούν να χρησιμοποιηθούν για να προσεγγίσουν κυλίνδρους πεπερασμένου μήκους [18], ενώ πεπλατυσμένα σφαιροειδή χρησιμοποιούνται για να προσεγγίσουν δίσκους [19]. Πολλοί ερευνητές έχουν όμως ασχοληθεί και με την σκέδαση επίπεδου ήλεκτρο μαγνητικού κύματος από ένα [20][21][22][23][24][25][26][27] ή και περισσότερα σφαιροειδή [28][29][30][31][32][33] αλλά και από σφαιροειδή που αποτελούνται από πολλές «στρώσεις» [34,35].…”
