Abstract: In this talk, I shall discuss the transformation optics based design of electromagnetic invisible cloaks from the inverse problems point of view. In order to avoid the difficulty posed by the singular structure required for ideal cloaking, we study the regularized approximate cloaking in prototypical models, for time harmonic Maxwell's equations in R3 and the scalar Helmholtz equations in R2. In particular, as the regularization parameter converges to zero, i.e., as the approximate cloaking converges to the ideal one, we will see that di fferent types of boundary conditions appearing at the interior of the cloaking interface. Some of them is of non-local pseudo-di erential type.
