geometrical is often used in a limited or strictly technical sense, as opposed to mechanical; thus, a construction or solution is geometrical which can be made by ruler and compasses, i. E, by means of right lines and circles. Every construction or solution which requires any other curve, or such motion of a line or circle as would generate any other curve, is not geometrical, but mechanical. By another distinction, a geometrical solution is one obtained by the rules of geometry, or processes of analysis, and hence is exact; while a mechanical solution is one obtained by trial, by actual measurements, with instruments, etc, and is only approximate and empirical. Geometrical curve. Same as Algebraic curve; so called because their different points may be constructed by the operations of elementary geometry. Geometric lathe, an instrument for engraving bank notes, etc, with complicated patterns of interlacing lines; called also cycloidal engine. Geometrical pace, a measure of five feet. Geometric pen, an instrument for drawing geometric curves, in which the movements of a pen or pencil attached to a revolving arm of ajustable length may be indefinitely varied by changing the toothed wheels which give motion to the arm.
(Science: geometry) geometrical plane, one of many species of spiders, which spin a geometrical web. They mostly belong to epeira and allied genera, as the garden spider. See garden spider. Geometric square, a portable instrument in the form of a square frame for ascertaining distances and heights by measuring angles. Geometrical staircase, one in which the stairs are supported by the wall at one end only. Geometrical tracery, in architecture and decoration, tracery arranged in geometrical figures.

Well Molecular Geometry is basically the geometrical arrangement of the atoms in a small or large molecule. In order to do this you will have to think back to some general chemistry. For this you need to know your hybridization states, primarily ...

The purpose is to use the method for guidance and optimization of the geometrical layout and for studying and improving the antenna robustness in a given environment. The most important parameters to investigate are the ...
