TY - JOUR ID - 2774 TI - Electromagnetic Wave Propagation in Square Law Wave Guides JO - Scientia Iranica JA - SCI LA - en SN - 1026-3098 AU - Hillion, P.

To solve Maxwell's equations in this wave guide, a paraxial approximation of the wave equations, satisfied by the electric and magnetic components of the electromagnetic field, has been used. The solutions of the corresponding paraxial wave equations describe beam propagation by a series expansion of Gaussian modes.
