Non-line-of-sight

Neutral species are best sampled using molecular beam methods in which the neutral beam is modulated between the sampling orifice and the ionization chamber of the mass spectrometer and only the modulated component of the mass spectrometer output is recorded. This approach enables all neutral species, including radicals to be detected with a comparable sensitivity. If modulation techniques are not used, the sensitivity for detecting condensible or reactive species is much less than for non-condensible, non-reactive neutral molecules because of the much larger effective pumping speed for the former in the mass spectrometer chamber. However, the ease of installation of non-line-of-sight non-modulated... 

Although sometimes differentiated from spray pyrolysis, aerosol assisted CVD is essentially the same motif. It is, however, typically not conducted in a flame type regime. Nevertheless, frequently, materials are not transported perpendicular to a substrate surface, thereby bypassing one of the crucial elements of chemical vapor deposition - the ability to secure extraordinary step coverage in high aspect ratio materials, due to the non-line-of-sight technique. 

Plasma treatment processes are usually reliable, reproducible, non-line-of-sight, and applicable to different sample geometries. 

Non-Line-Of-Sight Process Coating that is applied equally to all surfaces of a material, even inside convoluted shapes. 

Chemical vapor deposition CVD has the ability to coat complex shapes internally and externally because it is a non-line-of-sight process with strong throwing power... 

At microwave frequencies, non-line-of-sight paths can be estabhshed with the use of passive repeaters as well as active repeaters. At the millimeter wavelengths involved, passive reflectors can be constructed with sufficient gain to make their use practical. The most common passive repeater is a large, flat, billboardlooking reflector that acts exactly like an optical mirror. As with an active repeater, the passive repeater must have hne of sight to both the receiver and transmitter. A single passive reflector can not act as a relay when aU three components of the link are in-line or are nearly in-line. In such a case, two closely spaced passive reflectors are required.
