Electromagnetic Wave Propagation and Radiation in Chiral Media

摘要: Propagation and radiation of electromagnetic waves in a lossless, reciprocal, chiral medium is studied this thesis. Such described electromagnetically by the constitutive relations D = eE + iγB H iγE (1/µ)B. The constants e, µ, γ are real have values that fixed size, shape, spatial distribution elements collectively compose medium. plane wave propagation an unbounded considered. obtained polarization properties such discussed detail. problem reflection from, transmission through semi-infinite solved obtaining Fresnel equations. conditions for total internal incident from interface, existance Brewster angle obtained. effects chirality on intensity reflected half-space illustrated employing Stokes parameters. infinite slab formulated oblique incidence analytically case normal incidence. emitted oscillating dipole unbounded, calculated. From time-harmonic Maxwell equations ∇ x E iωB J - iωD, it seen equation given ω2µeE 2ωµγ∇ iωµJ where source term current density electric vector radiated field. desired solution found dyadic Green's function method, is, first constructing Γ then evaluating expression iωµ∫Γ(r,r')•J(r')dV'. components field closed form. B, D, fields can be derived knowledge using B (1/iω)∇ relations. impedance resistance also discussed.
