Scientific paper

The possibility of using electric antennae made of two small spheres to study the velocity distribution of charged dust grains in space are examined in this paper. The electric potential difference between the two spheres is determined by solving the Poisson's equation in a dusty plasma. Several examples of waveforms are shown. Typical dust grains with radii of 100 microns and signals of the order of 500 micorvolts are produced. The limitations due to the antenna and the plasma are also examined. A table summarizes the results under different conditions. It is concluded that, with a system of antennae, it is possible to detect (especially near comets and planetary ionospheres) dusts and to determine their velocity characteristics.
