Abstract :
The structure of transient electromagnetic radiation generated by line exponentially decaying current pulses propagating in lossy media is investigated. Description of the emanated waves in the space-time domain is obtained transferring the initial electromagnetic problem to a scalar one, separating the radial variable, using the Riemann formula and reducing the final multiple-integral solution into a simple quadrature taking advantage of the specific form of the integrand.
