abstract = {<p style="text-align: justify;">We consider high order methods for the one-dimensional Helmholtz equation and frequency-Maxwell system. We demand that the scheme be higher order even
when the coefficients are discontinuous. We discuss the connection between schemes
for the second-order scalar Helmholtz equation and the first-order system for the electromagnetic or acoustic applications.</p>},
