Modeling and Dealing with DISCONTINUTIES Assoc. Prof. Dr. imek Demir METU Dept of EEE Ankara Discontinuity EM fields either propagate in a guided medium or in free space The change of the propagation medium is a discontinuity Plane wave transition from vacuum to a dielectric medium Field in a transmission line experiencing step change in the line width CPW guided wave disturbed by a switch ...

Tunable transmission lines on silicon based upon periodic photonic bandgap structures Samir El Rai', Ralf Tempel', and Dieter Jager2 Abstract -- Differential transmission lines (DTL) can be synthesized as a chain of identical 2-Port unit cells UC. These DTL are interesting to use either for matching circuits or realizing small resonators serving in filters or oscillators. In this paper, we introdu

Transient analysis of metamaterial transmission lines Giulio Antonini Abstract -- This paper presents the transient analysis of metamaterial transmission lines. A ladder network model is used to simulate propagating and evanescent modes generated by negative permeability and permittivity. For such a kind of periodic structure quasi-closed form of poles and residues is presented leading to an effic

Prototype design of a dual-band dual-polarization Ku/Ka-band feed Hendrik A. Thiart', K. Rambabu2 and Jens Bornemann3 Abstract -- A design approach for a Ku/Ka-band satellite antenna feed prototype is presented. Band separation is achieved by employing a dielectrically loaded circular waveguide. To allow cost-effective integration with other components, etched probes formed from the same substrate
