Usage examples of "filamentary".
These filamentary structures are seen clearly in laboratory plasma discharges, solar prominences, and the shimmering draperies of the aurora, kinking and writhing unpredictably under their own internally generated fields, as fusion researchers trying to contain plasmas have learned to their consternation.
A proto-galaxy rotating in an intergalactic magnetic field would generate electric fields in the same way, which in turn would produce filamentary currents flowing inward through the galactic plane to the center, and then up along the rotational axis to loop back in a return path reentering around the rim.
Filippov, and an American, Joseph Mather, the device first compresses electrical energy a millionfold into a sub-millimeter-size donut of filamentary plasma called a plasmoid, and then collapses the associated magnetic field to shoot out two intense, high-energy beams, each in the order of a micron (one ten-thousandth of a centimeter) wide—electrons in one direction and ions in the other.
Beyond this, therefore, there should exist a further, larger structure of elongated, filamentary form, a billion or so light-years in radius and a few billion light-years long.
Every little ring was aligned the same way, along the filamentary arch.
