  We construct a regular isotropic approximate cloak for the Maxwell system of
equations. The method of transformation optics has enabled the design of
electromagnetic parameters that cloak a region from external observation.
However, these constructions are singular and anisotropic, making practical
implementation difficult. Thus, regular approximations to these cloaks have
been constructed that cloak a given region to any desired degree of accuracy.
In this paper, we show how to construct isotropic approximations to these
regularized cloaks using homogenization techniques, so that one obtains
cloaking of arbitrary accuracy with regular and isotropic parameters.
