This paper focuses on the concentric ring fractal array of the low side lobe characteristics in fractal antenna arrays.
You learn in grade school that each ring in a tree represents a year. But there's more information hidden away in these concentric rings.
Nevertheless, the first such ring was observed in 1987. Now, a group of astronomers led by Tommaso Treu of the University of California, Santa Barbara, have seen two concentric rings.
Results:When intussusception appeared as "multiple concentric rings", the reduction rate was 100%.
WIDE SHOT, moving in across the concentric rings of people, all plugged-in and softly chanting.
The "hill" around the center was only a meter tall now and shrinking rapidly as the concentric rings eased back to the floor of the room.
Dr Yabe's trick is to use relatively small Fresnel lenses-transparent and relatively thin planar lenses made up of concentric rings of prisms.
Its regular grid pattern is clearly visible at image upper left; concentric rings of major roadways around the city have been added as the metropolitan area has expanded.
Among those patterns there are bead-shape ones arranged in a circle, individual concentric rings, diamond rings, as well as sets of stacked rings, rings with radiation.
Track: (1) One of the concentric rings of a dise along which data is stored. (2) Refer to the space between letters in the computer typesetting program. A "loose track" means letter spacing, while a "tight track" means kerning.
