The lens is placed such that it produces a highly directional beam
The need for a narrow directional beam
to focus transmission power can further complicate efforts to achieve wide area coverage under non-line-of-sight conditions.
Santilli, Corporate Chief Scientist, states: "Following decades of mathematical, theoretical and experimental work as well as large private investment, we have achieved an operational equipment producing on demand a directional beam
of neutrons synthesized from the hydrogen gas in the desired flux and energy (http://thunder-energies.com/docs/dns1-info.pdf).
They use directional beam
arrays focused within a 15A spread, with more power directed to the devices and less exposure to interference from other networks.
After collimation, a directional beam
splitter (DBS) as described in Subsection 2.3 directs the laser light to the microscope.
HyperSound delivers high fidelity audio in a directional beam
using thin sound emitters.
Even though it shows a remarkable peak gain in front directional beam
patterns, it is rather cumbersome and, moreover, does not allow an omnidirectional pattern.
The LRAD can emit a highly directional beam
of sound at a pain-inducing 150 decibels.
Researchers from the Institute of Materials Research and Engineering (IMRE) in Singapore, and Imperial College London in the UK made T-rays into a much stronger directional beam
than was thought possible, and have clone so at room-temperature conditions.
The identification lobe of the reader is a directional beam
, offering precise determination of the detection area and solving multilane, entry, and exit reader challenges encountered in parking lots and secured areas.
