 | The ability to fully characterize a probe antenna using a near-field range is demonstrated subject to the conditions that two identical probes are available and that the E sub y field components are symmetric about the ky = O axis. A completely general three antenna approach, requiring no such assumptions, appears feasible. Some questions with respect to uniqueness of solution of the three antenna approach remain. Experimental results indicate that ... |

| The validity of the near-field measurement technique is the determination of the far-field radiation patterns of large phased arrays is demonstrated. The significance of accurately characterizing the near-field probe at all angles of interest is demonstrated. A new method of processing the Fast Fourier Transform has been developed that allows increased pattern resolution and reduced core memory requirements. The measurement of absolute gain has been carried out by a new ... |

| The results reported show that far-field antenna patterns determined on the near-field range are as accurate as those determined on a far-field range. The patterns of a single plane, monopulse antenna, operated at 5.45 GHz were measured on a near-field range and two different far-field ranges, and detailed comparisons were made. The results of a computer-aided simulation study to determine the effects of various near-field measurement errors on the far-field ... |

|
| Extremely low frequency (ELF) electromagnetic fields at 45, 60, and 75 Hz, up to 2 Gauss and 100 Volts/meter were explored for possible effects on operant behavior of pigeons and rats. No reliable effects were seen on a temporal discrimination procedure in which pigeons had to respond differentially depending upon the duration of a stimulus. Detection was explored in both pigeons and rats by attempting to use ELF fields as ... |
