In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1] In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°. Such species belong to the point group D 3h.
A Riemann surface is planar if and only if every closed 1-form of compact support is exact. [3] Let ω be a closed 1-form of compact support on a planar Riemann surface. If γ is a closed Jordan curve on the surface, then it separates the surface. Hence ∫ γ ω = 0. Since this is true for all closed Jordan curves, ω must be exact.
Planar transmission lines are transmission lines with conductors, or in some cases dielectric (insulating) strips, that are flat, ribbon-shaped lines. They are used to interconnect components on printed circuits and integrated circuits working at microwave frequencies because the planar type fits in well with the manufacturing methods for these ...
Tessellation in two dimensions, also called planar tiling, is a topic in geometry that studies how shapes, known as tiles, can be arranged to fill a plane without any gaps, according to a given set of rules. These rules can be varied.
"Substrate" might be defined. "the planar format fits in well with the manufacturing methods" could become "the planar format is easy to manufacture", etc. The Modes section could be made more accessible with some diagrams showing some modes, especially if those mode are superimposed with the planar circuit geometry. Those are my first impressions.
An important factor in the antiperiplanar conformer is the interaction between molecular orbitals. Anti-periplanar geometry will put a bonding orbital and an anti-bonding orbital approximately parallel to each other, or syn-periplanar.
The planar process is a manufacturing process used in the semiconductor industry to build individual components of a transistor, and in turn, connect those transistors together. It is the primary process by which silicon integrated circuit chips are built, and it is the most commonly used method of producing junctions during the manufacture of ...
Planar, the structure resulting from the planar process used in the manufacture of semiconductor devices, such as planar transistors; Planar graph, graph that can be drawn in the plane so that no edges cross; Planar mechanism, a system of parts whose motion is constrained to a two-dimensional plane
