Spacing of the fences needs to be small in comparison to a wavelength (λ) in the substrate dielectric so as to make the fence appear solid to impinging waves. If too large, waves will be able to pass through the gaps. A common rule of thumb is to make the spacing less than λ/20 at the maximum operating frequency. [6]
One of the most important properties of shape moiré is its ability to magnify tiny shapes along either one or both axes, that is, stretching. A common 2D example of moiré magnification occurs when viewing a chain-link fence through a second chain-link fence of identical design. The fine structure of the design is visible even at great distances.
Picket fences are a type of fence often used decoratively for domestic boundaries, distinguished by their evenly spaced vertical boards, the pickets, attached to horizontal rails. Picket fences are particularly popular in the United States, with the white picket fence coming to symbolize the ideal middle-class suburban life.

Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography ( Relièphographie ) for 3D autostereograms .
The dependence on the interference on clearance is the cause of the picket-fencing effect when either the radio transmitter or receiver is moving, and the high and low signal strength zones are above and below the receiver's cut-off threshold. The extreme variations of signal strength at the receiver can cause interruptions in the ...
The suggestion of the picket-fence concept did little, however, to dispel the atmosphere of gloom which settled over the conference, toward its end. The stability criterion which had been suggested by Teller was admittedly tentative, but it seemed dismayingly reasonable; perhaps more important, it brought the whole of the Sherwood program face ...
The correct number of sections for a fence is n − 1 if the fence is a free-standing line segment bounded by a post at each of its ends (e.g., a fence between two passageway gaps), n if the fence forms one complete, free-standing loop (e.g., enclosure accessible by surmounting, such as a boxing ring), or n + 1 if posts do not occur at the ends ...
