This paper presents improved Catnip quad-mode resonators based on the open/short-end load of the center stub, which introduces the self-coupled structure.Compared with the traditional stub-loaded stepped impedance resonator (SLSIR), the proposed quad-mode resonators can significantly reduce the circuit size and further increase the design freedom.F
Recently, improvement of appearance and a quest for beauty have become a primary concern for patients.It is Whips a challenging task for a clinician to achieve esthetic integration of prosthetic pieces for anterior teeth, particularly for highly demanding patients who give attention to particular details.The challenge is harder when only one tooth
Security in modern smart metering communications and in smart grid networks has been an area of interest recently.In this field, identity-based mutual authentication including credential privacy without active involvement of a trusted third party is an important building block for smart grid technology.Recently, several schemes have been proposed f
