Webcharacterized by a Bloch impedance Z B that varies spatially across the unit cell. It is important to note that the retrieved parameters for metamaterials are based on the spatially dis-persive Bloch impedance rather than the wave impedance 28 , so that B=n/Z B and B=nZ B, and will generally be ill-defined at points within the unit cell. Thus ...

WebMar 22, 2024 · The Bloch wave analysis can be performed through full wave analysis by considering an infinitely long structure. Here, Bloch impedance is extracted from N number of CRLH unit cells, i.e. by a finite unit cell approach as in [ [33], [34]] and is shown in Fig. 5. Mutual coupling is taken into account during analysis. WebThe Bloch impedance defined as the charac-teristic impedance of waves on the structure and so it is given by ZB = Z0 Vn+1 In+1. (9) From (4) we have (A −exp(γ du))Vn+1 +B ·In+1 = 0. (10) Therefore Z¯ B = ZB Z0 = − B A−eγd = − D −eγd C. (11) …
