A Point Source of Electromagnetic Waves in an Inhomogeneous Medium: a High Frequency Ansatz and the Dual Nonstationary Singular Solution

详细

The Maxwell equations for smoothly inhomogeneous media are addressed. The first-order term of the Hadamard-type expansion for the wavefield of a pulsed point source is presented. The Fourier transform in t of this expression allows for a high-frequency asymptotic formula for the wavefield of a point source of electromagnetic oscillations.
