(NRL) is developing technologies that will enable Navy-relevant missions with the smallest practical Micro Air Vehicles (MAVs). The NRL Micro Tactical Expendable (MITE) air vehicle is a result of this research. MITE is a hand-launched, dual-propeller, fixed-wing air vehicle, with a 25cm chord and a wingspan of 25-47cm, depending on payload weight. Vehicle(More)

The associated Legendre function arises naturally in the study of spherical waves. Since in practical applications it is most often symbolically represented by P<sub>n</sub> <sup>m</sup>(xi) for m les n and P<sub>n</sub> <sup>m</sup>(xi) equiv 0 for m &gt; n where m is the integer order and n is the integer degree, this form will be employed to develop the(More)
The gas of magnetic monopoles in spin ice is governed by one key parameter: the monopole chemical potential. A significant variation of this parameter could access hitherto undiscovered magnetic phenomena arising from monopole correlations, as observed in the analogous electrical Coulomb gas, like monopole dimerization, critical phase separation, or charge(More)
Two particularly accurate solutions representing the scatter of a Gaussian laser beam from a perfectly conducting cylinder, one a physical optics solution using a series Green's function and the other an exact solution, are developed. A comparison of their resulting numerical data follows in order to validate the two solutions. The practicality of these(More)

The expansion of electromagnetic sources is fundamental to the analysis of field propagation and scattering. Of these electromagnetic sources, one of the most commonly used optical sources is the narrow Gaussian beam. It is, therefore, useful to find an expansion of the narrow Gaussian beam that could be used in applications such as scattering and(More)
