A simple method to estimate mutual interaction of nearest neighbors in a compact planar array

In a planar array mutual interaction between neighboring radiators is more important when nearest neighbors are in contact or nearly so. Since it then becomes greatest at long wavelengths, a particular radiator shape has a limited effect on this maximum interaction. The method proposed consists of i...

Description
Summary:In a planar array mutual interaction between neighboring radiators is more important when nearest neighbors are in contact or nearly so. Since it then becomes greatest at long wavelengths, a particular radiator shape has a limited effect on this maximum interaction. The method proposed consists of investigating the transient field which results on an annular piston of radial width 2a from an impulsive velocity V
