In this paper, a MoM based numerical method is given to solve the 3D scattering problem including two lossy dielectric half space media separated by a 2D locally rough interface. The proposed method is the extended form of the buried object approach (BOA) method [2] to 2D rough surfaces. The method is very effective for locally rough surfaces having arbitrary surface variation. © 2011 IEEE. Source

The β-lactam ring of the title compound, C23H 18Cl2N2O5, is nearly planar [maximum deviation = 0.019(2)Å for the N atom] and its mean plane makes dihedral angles of 56.86(15), 68.83(15) and 83.75(15)° with the dichloro-, nitro- and methoxy-substituted benzene rings, respectively. In the crystal, molecules are linked by pairs of C - H⋯O hydrogen bonds, forming inversion dimers with R2(10) loops. The dimers are linked by further C - H⋯O hydrogen bonds, forming sheets lying parallel to (001). The molecular packing is further stabilized by C - H⋯π interactions. Source

In the title compound, C22H2 1N3O5, the-lactam (azetidin-2-one) ring is nearly planar [maximum deviation = 0.010 (1) Å] and makes dihedral angles of 69.22 (5), 55.32 (5) and 89.42 (4)-with the least-squares planes formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the xanthene ring system, respectively. In the crystal, C-H⋯O hydrogen-bond contacts connect neighbouring molecules into infinite zigzag chains running parallel to the b axis. Source

In the title compound, C26H27N3O 5, the β-lactam (azetidin-2-one) ring is nearly planar [maximum deviation = 0.011(3)Å]. The mean plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the naphthalene ring system form dihedral angles of 72.85(17), 87.46(15) and 65.96(11)°, respectively, with the β-lactam ring. In the crystal, molecules are linked via C - H⋯O hydrogen bonds, forming inversion dimers with R 2 2(8). Source

In the title compound, C12H13N3O, the morpholine ring adopts a chair conformation and its mean plane is inclined to that of the benzene ring by 16.78 (12)̊. The N-N C-C bridge, which has an E conformation, has a torsion angle of 173.80 (19)̊. In the crystal, molecules stack along the a axis but there are no significant intermolecular interactions present. Source
