G. Miaris et al., A UNIFIED FORMULATION FOR CHEBYSHEV AND LEGENDRE SUPERDIRECTIVE ENDFIRE ARRAY DESIGN, Electrical engineering, 78(4), 1995, pp. 271-280
A unified formulation for superdirective end-fire arrays by using Cheb
yshev and Legendre Polynomials and their maximum directivities as well
as the corresponding efficiency index and the Q factor are found. Sev
eral examples show the simplicity of the formulation.
