WebbThe short dipole antenna is the simplest of all antennas. It is simply an open-circuited wire, fed at its center as shown in Figure 1. Figure 1. Short dipole antenna of length L. The words "short" or "small" in antenna engineering always imply "relative to a wavelength". So the absolute size of the above dipole antenna does not matter, only the ... WebbThe theoretical plate concept is a good way to express relative efficiency, although it is important to understand that this model has limitations. When using the term …

WebbBond order is the number of chemical bonds between a pair of atoms and indicates the stability of a bond. For example, in diatomic nitrogen, N≡N, the bond order is 3; in acetylene, H−C≡C−H, the carbon-carbon bond order is also 3, and the C−H bond order is 1. Bond order and bond length indicate the type and strength of covalent bonds ... WebbThe effective length is the length between points of inflection (points of zero bending moment) on the buckled shape. Thus an actual column of length l with certain rotational …
