abstract = {<p style="text-align: justify;">This paper investigates the reduction of backscatter radar cross section (RCS)
for cavities embedded in the ground plane. It is established by placing a multilayered
radar absorbing material (RAM) at the bottom of the cavities. The minimization of the
backscatter RCS is formulated as a bound constrained optimization problem. A new
vertical mode expansion method is developed to solve the scattering problem, and
it is integrated into the gradient projection method to obtain the optimal composite
coating. Numerical examples show that the method we developed is efficient and the
backscatter RCS can be significantly reduced.</p>},
