An alternative uniplanar low-pa stubs is presented in this paper and its u extended up to five times of its cutoff frequenc structure primarily consists of short-circuited s line and connecting lines on coplanar waveguide of Chebyshev function low-pass frequency r element values involved in this filter topology efficient synthesis design approach rather try-t approach. Later on, the connecting ...

Colloidal aqueous suspensions of goethite lath-shaped nanorods form nematic and isotropic phases. We show that they also display a 2D rectangular (c2mm) columnar phase at volume fractions phi larger than 15%. Interestingly, the nematic-columnar first-order transition can also be triggered by applying to the nematic phase a magnetic field of intensity decreasing with phi (1 T at 8.5%; 0.5 T at 1...

Considering the glulam beam-column connection form and number of bolts, monotonic loading test finite element analysis was carried out on 9 specimens in 3 groups to study rotational performance failure mode connection. The results revealed that compared with U-shaped connectors, T-shaped connectors can effectively improve ductility connections, increase bolts reduce initial stiffness connection...

The electronic structure of recently discovered hollow-cage molecule T&C,, has been calculated and compared to similarly shaped hypothetical molecules M8Xi2 (M=metal and X= B, C, or N). The cohesion of the cage is related to the o-bonding between M-X arising from d-sp hybridization. It is also shown that the cage can become electronically closed shell with all the valence electrons paired when ...

We propose a new mirror architecture, which is solely based upon structuring of the surface of a monolithic, possibly monocrystalline, bulk material. We found that a structure of T-shaped ridges of a subwavelength grating can theoretically provide 100% reflectivity. Since no material needs to be added to the mirror device, lowest mechanical loss can also be expected. Our approach might have com...

Low-temperature photoluminescence-excitation spectra are studied in an n-type modulation-doped T-shaped single quantum wire with a gate to tune electron densities. With a nondegenerate one-dimensional (1D) electron gas, the band-edge absorption exhibits a sharp peak structure induced by the 1D density of states. When the dense 1D electron gas is degenerate at a low temperature, we observe a Fer...
