Electromagnetic form factors of the deuteron have been calculated by using the front-form formulation of relativistic particle quantum mechanics for momentum transfers between 0 and 8(GeV/c){sup 2}. A consistent relativistic calculation requires the construction of a Poincare invariant model of the deuteron as well as a Poincare covariant conserved current. In this framework conventional nucleon-nucleon interactions can be used to construct a fully relativistic wave function. Using empirical nucleon form factors as input a matrix representation of the conserved electromagnetic current is constructed. The transformation properties of this current are consistent with those of the wave functions. The sensitivity of the model to the choice of the nucleon-nucleon interaction, and to the uncertainty in the empirical nucleon form factors is tested by using Reid Soft Core, Paris and Argonne V14 nucleon-nucleon interactions and two different parameterizations of the empirical nucleon form factors. The results are compared to experimental data, to results from conventional non-relativistic models and to predictions from perturbative QCD.
