      Estimation of radio refractivity using a multiple angle clutter model

      Ali Karimian, Caglar Yardim, William S. Hodgkiss, Peter Gerstoft and Amalia E. Barrios

      Article first published online: 10 APR 2012 | DOI: 10.1029/2011RS004701

      Key Points

      • Incorporation of information of grazing angle in RFC
      • Multiple angle clutter better than single angle in RFC
      • Statistical analysis of 1998 SPANDAR data with the new model

      An extremely low profile, compact, and broadband tightly coupled patch array

      E. Irci, K. Sertel and John L. Volakis

      Article first published online: 18 JAN 2012 | DOI: 10.1029/2011RS004771

      Key Points

      • Broadband antennas are formed using tightly coupled and excited elements
      • The resulting array is an active FSS and is more broadband than EBGs
      • These arrays are also much more broadband than conventional patch antennas

      Article first published online: 25 OCT 2011 | DOI: 10.1029/2011RS004689

      Key Points

      • MPI/GPU parallelization for time-domain Maxwell's equations
      • Parallelization of discontinous Galerkin time-domain methods
      • Combination of local time-stepping with MPI/GPU parallelization

      M. Harun and S. W. Ellingson

      Article first published online: 18 OCT 2011 | DOI: 10.1029/2011RS004710

      Key Points

      • Low frequency strut-straddling feed arrays for EVLA reflector antennas
      • Radio astronomy
      • Reflector antenna feed for low frequency operation

      Analysis of time-of-arrival observations performed during ELF/VLF wave generation experiments at HAARP

      S. Fujimaru and R. C. Moore

      Article first published online: 20 SEP 2011 | DOI: 10.1029/2011RS004695

      Key Points

      • Time-of-arrival (TOA) analysis is applied to ELF/VLF observations
      • TOA yields ability to separate direct and ionospherically reflected components
      • TOA may provide ability to characterize the ELF/VLF source region currents

      World coverage for single station lightning detection

      C. Mackay and A. C. Fraser-Smith

      Article first published online: 25 MAY 2011 | DOI: 10.1029/2010RS004600

      Key Points

      • Analyzes limitations to single station lightning location
      • Displays world coverage of lightning detected by single station
      • Compares expected and measured lightning detected by a single station
