| In this paper we present a novel approach for the incorporation of wavelets into the solution of frequency-domain integral equations arising in scattering problems. In this approach, we utilize the fact that when the basis functions used are wavelet-type functions, only a few terms in a series expansion would be needed to represent the unknown quantity. Moreover, an iterative procedure is sug...
متن کامل133 IEEE TRANSACTIONS ON ANTENNAS AhTD PROPAGATION
Hershberger' raised the question of xvhether a multiplicit>. of resonances had been observed in radio reflections from meteor trails at frequencies near the plasma frequency similar to those observed from positive columns in the laboratory. Nolv that a theoretical description of the process leading to the laboratory observations is available2 one can determine whether such resonances...
متن کاملA Dual-Polarized Slot Antenna for Millimeter Waves - Antennas and Propagation, IEEE Transactions on
We describe a new dual-polarized slot antenna to be used with quasi-optical devices such as superconductor-insulatorsuperconductor (SIS) mixers at millimeter and submillimeter wavelengths. The radiation and impedance characteristics of the antenna were obtained from a moment-method calculation. The antenna has an excellent radiation pattern, a low impedance, wide bandwidth, and low cross polari...
متن کاملOn the design of maximally sparse beamforming arrays - Antennas and Propagation, IEEE Transactions on
The problem of designing nonuniformly spaced arrays is formulated as one of constrained optimization in which the cost function is chosen to select the array with the minimum number of elements. The response of the array is controlled by a set of inequality point response constraints. It is shown that a suitable cost function for this problem is the I,, quasi-norm for 0 < p < 1 and that there e...
متن کاملA Compact Antenna Test Range Based On A Hologram - Antennas and Propagation, IEEE Transactions on
The application of conventional reflector-type compact antenna test ranges (CATR’s) becomes increasingly difficult above 100 GHz. The main problems are the tight surface accuracy requirements for the reflectors and, therefore, the high manufacturing costs. These problems can be overcome by the use of a hologram type of compact range in which a planar hologram structure is used as a collimating ...
