  A virtual element method (VEM) with the first order optimal convergence order
is developed for solving two dimensional Maxwell interface problems on a
special class of polygonal meshes that are cut by the interface from a
background unfitted mesh. A novel virtual space is introduced on a virtual
triangulation of the polygonal mesh satisfying a maximum angle condition, which
shares exactly the same degrees of freedom as the usual
$\bfH(\curl)$-conforming virtual space. This new virtual space serves as the
key to prove that the optimal error bounds of the VEM are independent of high
aspect ratio of the possible anisotropic polygonal mesh near the interface.
