In 2001, Bridgeman et al. synthesized a rare species having a T-shaped phosphorus atom centering an organometallic cluster, [{Cp(OC)2Mo}2PMn(CO)4]. Our DFT and extended Hückel electronic structure calculations indicate that the T-shaped geometry results from an unusual Mo-Mn-Mo three-center, two-electron bond that "ties" back the two-center, two-electron Mo-P bonds. Additional stabilization of ...

In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave-expansion (PWE) techniques. Photonic crystals (PhCs) are artificial dielectric nanostructure materials in which a periodic modulation of the material ...

─ A simple and compact microstrip-fed ultra wideband (UWB) slot antenna with dual band-notch characteristic for UWB applications has been presented. In order to increase the impedance bandwidth of the square slot antenna, we insert a T-shaped slot in the ground plane that with this structure UWB frequency range can be achieved. Additionally, by using a pair of Lshaped slits at the square radiat...

In this paper, the study on multi-storied building with and without expansion joint when it is subjected to seismic forces in both x y direction are taken into consideration. By maintain same floor area of different plans provided along weaker column stretch stiffed order make more resistant compared joints. The analysis done using ETABS 2016. parameters such as shear force bending moment at cr...

In this manuscript, a novel design of ultra-wideband (UWB) monopole antenna with dual frequency band-stop performance is proposed. The proposed antenna consists of an ordinary square radiating patch with a pair of rotated T-shaped slits, and a modified ground plane with an inverted Ω-shaped and a pair of rectangular-ring slots. In the presented structure, by cutting a pair of rectangularring sl...
