Abstract : Electromagnetic wave propagation in a medium with an exponentially increasing charge density is studied. Both transmitted and reflected fields are found in the case of plane, monochromatic waves. The use of the bilateral Laplace transform allows the transforms of the transmitted and reflected fields to be found in the case of a stepfunction excitation moving with velocity co previous to entering the exponential medium. The reflected and transmitted fields are found explicitly when the Bessel functions obtained as solutions can be expanded asymptotically for small argument. (Author)
