IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishReflection of normally incident microwaves from a novel quasi-periodic High Impedance Surface is investigated. The quasi-periodic surface is formed by cascading similar, width-modulated microstrip line based unit cells. Parameter values in individual cells are changed to make the surface quasi-periodic. The reflections from quasi-periodic structures formed using sequences of different but similar unit cells are compared with the reflection from a truly periodic structure formed by identical unit cells. The effect of the order inside the quasi-periodic sequence is discussed. The proposed novel method enables efficient control the reflection phase and hence helps to reduce the design time for holographic surfaces and reflectarrays.

| Abstract: | Reflection of normally incident microwaves from a novel quasi-periodic High Impedance Surface is ...investigated. The quasi-periodic surface is formed by cascading similar, width-modulated microstrip line based unit cells. Parameter values in individual cells are changed to make the surface quasi-periodic. The reflections from quasi-periodic structures formed using sequences of different but similar unit cells are compared with the reflection from a truly periodic structure formed by identical unit cells. The effect of the order inside the quasi-periodic sequence is discussed. The proposed novel method enables efficient control the reflection phase and hence helps to reduce the design time for holographic surfaces and reflectarrays. | |
