Time-dependent Beltrami fields in free space follow very naturally from the Maxwell postulates. In this paper, a comprehensive but elementary treatment of time-dependent Beltrami fields in material continua is enunciated. Field equations in free space have been derived and solved, and a scheme for the general representation of Beltrami fields has been given. Field relations in material continua have been set up in the form of Beltrami-Maxwell postulates, along with appropriate constitutive relations for linear materials. Monochromatic Beltrami field formulation in free space as well as in linear materials has been accomplished. The Mossotti-Clausius model, to enable the transition from the microscopic to the macroscopic length scales, has been given entirely in terms of Beltrami fields.
