The problem of the diffraction of electromagnetic waves by a circular aperture in an infinitely conducting planar screen is studied. Attention is focused chiefly on the low frequency end of the ...

The Quarterly of Applied Mathematics contains original papers in applied mathematics which have a close connection with applications. An author index appears in the last issue of each volume. This ...

Angular spectrum methods constitute a powerful framework for simulating wave propagation and diffraction phenomena in optical systems. By decomposing a complex wavefield into its constituent plane ...

Google Earth provides a cornucopia of exotic images of our planet taken from above. For the most part, the focus of attention is on the land and the cities, roads and natural formations that it ...

IT has been well established by several investigators 1,2 that, in the case of diffraction of light by ultrasonic waves, the first orders of diffraction on either side of the central zero order appear ...
