free-space propagation
11Line-of-sight propagation — refers to electro magnetic radiation including light emissions traveling in a straight line. The rays or waves are diffracted, refracted, reflected, or absorbed by atmosphere and obstructions with material and generally cannot travel over the… …
12Fruit tree propagation — is usually carried out through asexual reproduction by grafting or budding the desired variety onto a suitable rootstock. Perennial plants can be propagated either by sexual or vegetative means. Sexual reproduction occurs when male pollen from… …

15Path loss — (or path attenuation) is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system.This term… …
16Okumura Model — The Okumura model for Urban Areas is a Radio propagation model that was built using the data collected in the city of Tokyo, Japan. The model is ideal for using in cities with many urban structures but not many tall blocking structures. The model …
17Fresnel diffraction — In optics, the Fresnel diffraction equation for near field diffraction, is an approximation of Kirchhoff Fresnel diffraction that can be applied to the propagation of waves in the near field.[1] The near field can be specified by the Fresnel… …
18Arrayed waveguide grating — Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing a large number of wavelengths into a single optical fiber, thereby… …
