1 Furse, Cynthia M.Broadband and multiband antenna design using the genetic algorithm to create amorphous shapes using ellipsesA method is demonstrated for generating compact, broadband and multiband antennas using ellipses to create new amorphous shapes with greater bandwidth and less return loss that previously demonstrated. Four designs are presented including a tri-band patch antenna optimized for low reflection loss a...Broadband antenna design; Multiband antenna design; Ellipses2006-10
2 Furse, Cynthia M.; Lazzi, Gianluca; Gandhi, Om P.Comparison of FDTD computed and measured radiation patterns of commercial mobile telephones in presence of the human headIn this letter, finite-difference time-domain (FDTD) computed radiation patterns of mobile telephones are carefully compared with those measured in our laboratory. The question on the capability of the FDTD method to correctly predict the radiated electromagnetic fields of today's structurally comp...FDTD; Finite-difference time-domain; Mobile antennas1998-01-01
3 Furse, Cynthia M.; Gandhi, Om P.Computations of SAR distributions or two anatomically based models of the human head using CAD files of commercial telephones and the parallelized FDTD codeA method for importing data from computer-aided design (CAD) files for a mobile telephone into finite-difference time-domain (FDTD) simulation software is described. Although the FDTD method is well suited for the bio-electromagnetic simulations and has become the method of choice for most research...Specific absorption rates; SAR; CAD files; FDTD; Finite-difference time-domain1998-01-01
4 Furse, Cynthia M.Impedance of a short dipole antenna in a magnetized plasma via a finite difference time domain modelThe traditional analytical analysis of plasma probes requires the use of quasi-static approximations, while numerical methods require the use of an equivalent dispersive media, both producing a nontrivial analysis of the plasma environment. On the other hand, a few techniques that combine the plasm...Antenna theory; finite-difference time-domain; FDTD; Plasma covered antennas; Plasma measurements2005-08
5 Furse, Cynthia M.Miniaturized biocompatible microstrip antenna using genetic algorithmBiocompatible antennas are an area of recent research that can facilitate remote communication with medical implants. This paper shows several possible designs of a "waffle-type" antenna created using genetic algorithms (GAs) that are of a size potentially suitable for cardiac pacemakers in the 40...Biocompatible antennas; Pacemaker antenna; Medical telemetry devices2005-06
6 Furse, Cynthia M.Optimization of a buried microstrip antenna for simultaneous communication and sensing of soil moistureImbedded microstrip antennas have been previously demonstrated for use either as sensing elements or as components of a wireless communication system. This paper presents a method and dual use designs for simultaneous sensing of soil moisture and communication from the buried antenna to an external...Finite-difference time domain; FDTD; Automatic sprinkler control systems2006-03
7 Furse, Cynthia M.; Christensen, Douglas A.Problem and treatment of DC offsets in FDTD simulationsThis paper discusses the causes of and some solutions to the commonly observed problem of dc field offsets in finite-difference time-domain (FDTD) simulations. DC electric and magnetic field offsets are shown to be valid calculated responses of the modeled systems, resulting from interaction betwee...FDTD simulations; Finite-difference time-domain; DC offsets2000-01-01

9 Furse, Cynthia M.Prof. James R. wait and mining production technology--an appreciationProf. James R. Wait examined electromagnetic (EM) wave propagation in many situations of interest to mining production, including propagation in tunnels, propagation along extended conductors such as cables and drill stems, and propagation in coal seams. This work remains relevant, both to the mini...James R. Wait; Electromagnetic wave propagation; Geologic measurements; Mining industry2000-09
10 Furse, Cynthia M.Recovering handset diversity and MIMO capacity with polarization-agile antennasDesign guidance is provided for multiple-input-multiple- output (MIMO) antenna systems on handsets-a strong prospect for next generation wireless devices. Handheld wireless devices are likely to be rotated out of their optimal polarization, thereby experiencing significant power losses. An existin...Adaptive arrays; Diversity methods; Multiple-intput-multiple-output; MIMO; Handset diversity; Handheld devices; Polarization agile antenna2007-11
