abstract = {<p style="text-align: justify;">This paper develops and analyzes interior penalty discontinuous Galerkin
(IPDG) method by patch reconstruction technique for Helmholtz problems. The technique achieves high order approximation by locally solving a discrete least-squares
over a neighboring element patch. We prove a prior error estimates in the $L^2$ norm
and energy norm. For each fixed wave number $k,$ the accuracy and efficiency of the
method up to order five with high-order polynomials. Numerical examples are carried
out to validate the theoretical results.</p>},
