Ba0.5Sr0.5TiO3 (BST-0.5) thin films (600 nm) were deposited on single crystal MgO, SrTiO3 (STO), and LaAlO3 (LAO) substrates by pulsed laser deposition at an oxygen partial pressure of 80 mTorr temperature 720 °C. X-ray diffraction in situ reflection high-energy electron routinely ascertained the epitaxial quality (100)-oriented nanocrystalline films. The broadband microwave (1–40 GHz) dielectr...

BACKGROUND To compare non coplanar field (NCF) with coplanar field (CF) -intensity-modulated radiotherapy (IMRT) planning for ethmoid cancer. METHODS Seven patients treated with NCF IMRT for ethmoid cancer were studied. A CF IMRT optimization was prepared with the same constraints as for the NCF treatment. The maximum point doses (D max) obtained for the different optic pathway structures (OP...

A new approximation technique to find the total series impedance per unit length for quasi-TEM transmission lines including conductor loss has been developed. It is shown through the use of conformal mapping that both frequency dependent skin-depth and proximity effects can be accurately modeled. Comparison between experimental measurements and calculations for twin-lead, coplanar strips, paral...

The aromatic ring of the title compound, C(6)H(3)ClN(2)O(5), is almost planar (r.m.s. deviation = 0.007 Å); one nitro substituent is nearly coplanar with the ring [dihedral angle = 3(1)°], whereas the other is twisted [dihedral angle = 36 (1)°]. The phenol OH group is intra-molecularly hydrogen bonded to the nitro group that is coplanar with the ring, generating an S(6) graph-set motif.

In the title compound, C(17)H(13)F(3)N(2)O(2), the two aromatic rings are essentially coplanar, forming a dihedral angle of 2.78 (12)°. The non-H atoms of the eth-oxy group are coplanar with the attached ring [maximum deviation = 0.271 (3) Å]. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure, mol-ecules are linked by inter-molecular C-H⋯N and C-H⋯F hydrogen bonds.

The dihydro-pyrimidine ring of the title compound, C(13)H(15)ClN(2)S, adopts an envelope conformation with five almost coplanar atoms (r.m.s. deviation = 0.054 Å) and the C atom bearing the two methyl substituents deviating from this plane by 0.441 (2) Å. The best plane through the five almost coplanar atoms forms a dihedral angle of 89.56 (5)° with the benzene ring. The crystal packing is char...

A new 6-port “circuit-model” for Coplanar-Slotline Crosses is presented. The model is based on the separation of the two fundamental Coplanar Waveguide (CPW) modes (even and odd) into different ports. It generalizes previous models since it explains the Cross’ behavior even if air-bridges are not used and Slotlines are loaded asymmetrically. The new model is applied to the analysis of the -para...
