  We present an arbitrary order discontinuous Galerkin finite element method
for solving the fourth-order curl problem using a reconstructed discontinuous
approximation method. It is based on an arbitrarily high-order approximation
space with one unknown per element in each dimension. The discrete problem is
based on the symmetric IPDG method. We prove a priori error estimates under the
energy norm and the L^2 norm and show numerical results to verify the
theoretical analysis.
