Is exercise 4, part b of chapter one of Ashcroft and Mermin wrong?

This is from Solid State Physics. It is about helicon waves in a metal. When I take the curl of the given electric field it does not equal zero even though the magnetic field is static. Is this an er …

How can there be an electric field normal to the surface in a surface plasmon in a metal

Ashcroft and Mermin's Solid State Physics, chapter one, has an exercise about surface plasmons. They give the electric field normal to the surface of the metal as $E_z=Be^{iqx}e^{-Kz}$ How can this be …
