Plane wave scattering from two closely spaced, closed, active, cylindrical coated nano particles (C-CNPs), which have slightly different resonance frequencies, is studied numerically. Although the distance between them is only 0.4λ, the scattering cross-section(SCS) background value of this two-C-CNP system is increased 5dB when r2 = 15.1 nm and the 3dB SCS bandwidth is increased to 150 GHz, which is a substantially wider working bandwidth near the SCS peak than the one associated with either
