Low-Observable Reflectors Using Perfect Pulses

This paper presents a new technique for suppressing specular reflection using binary reflective surfaces (such as those easily fabricated on a printed circuit board)that maximally suppress mean currents on the reflector using the theory of perfect pulses. We simulate multiple versions (or orders)of these structures to characterize the nulling depth and manufacturing tolerance of the designs. In addition, we run another set of simulations to characterize the specular reflection as a function of the direction of incidence. The simulation reveals that the specular reflection from the proposed structures is at least 9.3 dB less than that from a flat metal plate of the same dimensions.
