Bazant and Oh  based on their experimental results, suggested to use a minimum beam width
of three times maximum aggregate size (da) used in testing, as the width of fracture process zone of the concrete is three times maximum size of aggregate.
The 18 dBi antenna was also always questioned both for its narrow vertical beam width
and also its horizontal beam width
of "only" 65[degrees].
Based on the method, an exact analytical description of the variation of the RMS beam width
75 dB within the entire beam width
of the 2 x 2 sub-array.
the synthesized pattern is not of minimum beam width
for a specified side lobe level.
Moreover the HPBW of each beam is reported in order to demonstrate the proper functioning of the proposed switched-beam antenna, in terms of overlapping area and beam width
The Reactor TL taclight features Radiance lightbeam technology, which compresses energy into a wide, horizontal light field, with no energy wasted above or below the target area, and features more than twice the common beam width
The second is the Lasar 40 active/passive system based on a network of arrays, the transmitter operating in the 30 to 45-kHz band with a horizontal beam pattern of 180[degrees], 270[degrees] or 360[degrees] for seabed mounting and jetty wall mounting, a vertical beam width
of 3[degrees] to 10[degrees] and vertical beam steering of [+ or -] 10[degrees].
Aerial View also provides detailed numerical analysis of directivity, beam width
, beam efficiency, vertical tilt, horizontal rotation, and more.
It offers a choice of light colour, beam width
-- narrow and medium -- and is available as a complete range: surface-mounted, recessed, semi-recessed, wall-mounted and desktop.
lambda]], beam width
remains stable practically in the entire scanning aperture range [D.
Unlike microwave, however, MMW technology uses a narrow, one-degree beam width
, so it has less potential for interfering with other signals than microwave, allowing for a simple and inexpensive licensing scheme.
