Abstract
The straightforward method of transformation optics implies that one starts from the coordinate
transformation and determines the Jacobian matrix, the fields and material parameters of the
cloak. However, the coordinate transformation appears as an optional function: it is not
necessary to know it. We offer the solution of some sort of inverse problem: starting from the
fields in the invisibility cloak we directly derive the permittivity and permeability tensors of the
cloaking shell. This approach can be useful for finding material parameters for the specified
electromagnetic fields in the cloaking shell without knowing the coordinate transformation.
