The flnite-difierence frequency-domain (FDFD) method with the adaptive basis functions/diagonal moment matrix (ABF /DMM) technique is proposed in this paper for flnite periodic linear arrays of inhomogeneous dielectric cylinders, in which the versatility of the FDFD method and the high e-ciency of the ABF/DMM technique are combined. The method in this paper and the classical full- domain FDFD method are compared in the given numerical examples. The results obtained by the two methods respectively are in good agreement, but the computational times are largely reduced in the method in this paper.
