As the width of short-wave broadcasting bands increases the problem of matching arrays is becoming more important. It is desirable to match the array to the transmission line over the whole band ...

Abstract Measurements are described which have been made to determine the reduction in the distant field strength when obstacles disturb the radiation from a high-frequency curtain array ...

Through precision calibration via an orbiting beacon and exquisite foreground characterization, the farside array would measure the Dark Ages global 21-cm signal at redshifts z~35-200. It will also be ...

Abstract: This is the final report submitted to NASA for a Probe-class concept study of the "Farside Array for Radio Science Investigations of the Dark ages and Exoplanets" (FARSIDE), a low radio ...

Four frequencies of each cytotype were tested, and pollinators consistently overvisited rare cytotypes. Seed yield and F1 hybrid production were greater in 4X-6X arrays than 2X-4X arrays, whereas ...
