A general 2-D problem of electromagnetic scattering from a multiple cavitybacked longitudinally loaded slotted perfectly conducting cylinder with arbitrary cross section is formulated. The formulation is used to account for the scattered field from the scale models,for which,a series of experiments has been conducted in an anechoic chamber. Excellent agreement between theory and experiment is obtained. The analysis of the experimental results near resonant frequency shows that the reduction of backscattering radar cross section over wide aspect angles,and the obvious enhancement of target angular glint (linear deviation) can be achieved by the impedance loading such as multiple cavity-backedslots,which realizes a new stealth technique for vehicles.
