Enrichment of EBG contents of periodic structures by geometry modulation

Designing periodic structures with novel properties related to propagation of electromagnetic waves presents interest for applications in antenna technology, dispersion engineering, filtering, signal integrity etc. We consider a periodic structure built in stripline technology and assess the effect of geometry modulation on the dispersion diagram, including newly introduced modes and electromagnetic band-gaps. We relate the dispersion diagrams of the modulated and unmodulated structures. Results present interest for applications in the above mentioned fields.
