  Rapid heating of small buried regions by laser generated fast electrons may
be useful for applications such as XUV radiation sources or as drivers for
shock experiments. In non-structured targets the heating profile possesses a
global maximum near the front surface. This paper presents a new target design
that uses resistive guiding to concentrate the fast electron current density at
a finite depth inside the target. The choice of geometry uses principles of
non-imaging optics. A global temperature maximum at depths up to 50{\mu}m into
the target is achieved. Although theoretical calculations suggest that small
source sizes should perform better than large ones, simulations show that a
large angular spread at high intensities results in significant losses of the
fast electrons to the sides. A systematic parameter scan suggests an optimal
laser intensity. A ratio of 1.6 is demonstrated between the maximum ion
temperature and the ion temperature at the front surface.
