Abstract
In this paper, several families of irreducible constacyclic codes over finite fields and their duals are studied. The weight distributions of these irreducible constacyclic codes and the parameters of their duals are settled. Several families of irreducible constacyclic codes with a few weights and several families of optimal constacyclic codes are constructed. As by-products, a family of irreducible cyclic codes over and a family of irreducible cyclic codes over are presented, where is a prime such that . The results in this paper complement earlier works on irreducible constacyclic and cyclic codes over finite fields.
