A two dimensional Finite Difference Frequency Domain (2D-FDFD) eigenanalysis of an array consisting of periodically located strips printed on axially magnetized ferrite film is presented. The main interest in these structures arises from our previous study which revealed their support of backward surface and possibly backward leaky waves. Moreover these structures exhibit non-reciprocal phenomena. These phenomena are studied thoroughly by using our two - dimensional curvilinear frequency domain finite difference (2D-FDFD) method, modified appropriately for the eigenanalysis of periodic structures. The present effort is particularly focused on the study of the non-reciprocal phenomena involved in periodic structures loaded with magnetized ferrites.
