Printed Periodic Waveguide Structures

Printed periodic waveguide structures present an in-depth study on the guided-wave characteristics and applications of periodic waveguide structures loaded with printed strips and slots. From the full-wave analysis of a single unit/cell of the periodic waveguide structure using the Hybrid MoM-Immittance Approach, guided-wave per-unit length transmission parameters of frequency selective surface (FSS) printed periodic waveguide structures are numerically obtained. It has been observed that different FSS loading configurations exhibit distinctive guided-wave characteristics such as slow-wave, fast-wave, backward wave, forward wave, etc. Such printed periodic waveguide structure can be used for various applications. It has been demonstrated that such periodic waveguide structures can be used for constructing performance enhancedwaveguide filters, compact and wideband EBG transmission media and waveguide basedDNG metamaterials.
