  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 H(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.
