OBJECTIVES To compare the polymerization contraction stress of resin cements in dual-cure and self-cure modes, and verify its effect on microleakage and gap formation in class I cavities restored with porcelain inlays. METHODS Dual-cure cements (Calibra, Choice and RelyX ARC) were monitored for contraction stress during 30 min in the tensilometer, in the presence or absence of photo-activatio...
In this paper, a novel structure of One-Third-Mode Substrate Integrated Waveguide Resonator (OTMSIWR) is first proposed, which reduces about 65% size. Based on the OTMSIWR, a single-band bandpass filter (BPF) operats at 4.55GHz is designed. The single-band BPF has a wide and deep upper stopband. Further, a dual-band BPF using high mode technology based on the single-band filter is designed. The...
In this work, an electronically reconfigurable dual-band dual-mode microstrip ring antenna with high isolation is proposed. Using characteristic mode analysis (CMA), the physical characteristics of are revealed, and two modes appropriately chosen for operation in sub-6 GHz “legacy” bands. Due to inherent orthogonality modes, measured larger than 37 dB was achieved both bands without requiring c...
