Field Trip to a Galaxy Far, Far Away
Journal of Geoscience Education, 2000The fictional worlds of the Star Wars universe can be effectively used as teaching examples in planetary science. Because of the immense popularity of the Star Wars series, most students are already familiar with the movies and the worlds featured in them. Using fictional planets as teaching tools provides a context in which there are no right or wrong

Tolerance on defocus precisely locates the far field (exactly where is that far field anyway?)
Applied Optics, 2002The Fraunhofer criterion defines the location of the boundary between the Fresnel and the Fraunhofer diffraction regions and thus determines the location of that region commonly referred to as the far field. The Fraunhofer criterion is usually given as an axial distance much greater than some amount relative to the maximum dimension of the aperture. By

Far Field Splitting for the Helmholtz Equation
SIAM Journal on Numerical Analysis, 2014Given far field data of a time-harmonic wave radiated by an ensemble of well separated acoustic or electromagnetic sources as well as a priori information on the locations of these sources, we discuss an algorithm to approximate the far field data radiated by each of these sources separately.

Far field somatosensory potentials in the rat
Electroencephalography and Clinical Neurophysiology, 1977Averaged somatosensory evoked potentials (SEPs) in the rat were recorded from skull electrodes. The cortical component of the SEP was preceded by at least three low amplitude potentials. Surface distribution of these potentials, correlation with depth recording from posterior columns, posterior column nuclei, inferior cerebellar peduncle, medial ...

Although the microscope image comparator was designed for quantifying the severity of surface imperfections, its ability to measure luminosity values of any image and compare values with images of similar objects suggests there may be other uses for this instrument.

Near-field to far-field transformation
2016In previous chapters, the finite-difference time-domain (FDTD) method is used to compute electric and magnetic fields within a finite space around an electromagnetic object (i.e., the near-zone electromagnetic fields). In many applications, such as antennas and radar crosssection, it is necessary to find the radiation or scattered fields in the region ...
