We propose a method for adaptive waveguide bends using homogeneous, nonmagnetic, and isotropic materials, which simplifies the parameters of the bends to the utmost extent. The proposed bend has an adaptive and compact shape because of all the flat boundaries. The nonmagnetic property is realized by selecting OB'/OC = 0.5. Only two nonmagnetic isotropic dielectrics are needed throughout, and the transmission is not sensitive to nonmagnetic isotropic dielectrics. Results validate and illustrate these functionalities, which make the bend much easier to fabricate and apply, owing to its simple parameters, compact shape, and versatility in connecting different waveguides.
我们提出了一种使用均匀、非磁性和各向同性材料的自适应波导弯曲方法，该方法将弯曲的参数最大限度地简化。由于所有的平坦边界，所提出的弯曲具有自适应和紧凑的形状。通过选择 OB'/OC = 0.5 来实现非磁性。整个过程只需要两种非磁性各向同性电介质，并且传输对非磁性各向同性电介质不敏感。结果验证并说明了这些功能，这使得弯曲更容易制造和应用，因为它的参数简单、形状紧凑且在连接不同波导方面具有多功能性。
