Dual Band RCS Reduction Using Modulated Grooves in A Conducting Plane
- 3 Downloads
An electromagnetic boundary-value problem of modulated grooves in a conducting plane is rigorously solved based on the Fourier transform, eigenfunction expansion, and mode matching method. Radar cross section (RCS) of the modulated grooves is represented in a series form and calculated while varying depth, width, and period of the grooves to investigate scattering characteristics of dual band RCS reduction.
