MAPHUB
MapHub allows users to display maps and perform various operations on them. Over one hundred maps are included, from the popular Mercator and Elliptical maps to the rarer ABC and XYZ maps. Users can add cities, calculate distances, trace country or continent lines, superimpose user-defined contours, create interrupted maps, and perform various other functions. In addition, users can import digital maps and other data files and export maps and map data to external files for use in other programs. |

FiMA
Allwave Corporation announces a new release on May 1, 2014 of software package FiMA®, v.1.0, for the simulation and implementation of electromagnetic holography.
Summary
FiMA® provides exact, closed-form solutions, based upon Allwave’s proprietary Field Mapping Algorithm, to the problems of electromagnetic holography based upon near zone data acquired on any one of following surfaces: a) plane, b) sphere, c) cylinder, d) enclosing rectangular box, or e) enclosing cylinder. This software package serves as a powerful design and simulation tool for both analytic and measured data. Users from a broad spectrum of scientific communities will be gratified to discover here a considerable utility across a wide range of applications, such as microwave holography, imaging, inverse scattering, near zone field reconstruction and 3D visualization, materials testing, antenna diagnosis, synthesis, and design, ISAR, EMI/EMC, and EM wave propagation in general.
FiMA® Supports a Wide Range of Applications wherein it
- Antenna diagnosis/synthesis/design
Determines exact source region fields directly from near-field data, as an aid to antenna surface or feed element diagnostics, as well as synthesis/design.
- Closed-form near-to-near, near-to-far, and far-to-near field transforms
Provides near-field to near-field transformations from five different surfaces to any surface; near-field to far-field from five surfaces; and far-field to near-field over any arbitrary surface, including probe corrections and data enhancement through Nyquist sampling.
- Microwave photography: a snapshot of microwaves
Invokes exact solutions so as to enable a single slice of near-field data to unfold into a full 3D visualization of electromagnetic wave propagation.
- Microwave imaging
Provides a powerful tool for single-frequency microwave imaging.
- RCS & ISAR
Determines the geometry of aircraft based on one slice of single-frequency near-field data, altogether free from wide-band requirements.
- Materials measurement
Determines material properties from either transmitted or reflected near-field data.
- EMC/EMI detection
Identifies noise and interference sources via one slice of near-field data.
- Wave diffraction phenomena
Obtains diffraction fields around objects from a given slice of near-field data: it’s real!
Shaping
Allwave Corporation is poised to announce a new release on October 1, 2017 of software package Shaping®, v.1.0, a reflector shaping design tool for meeting arbitrary far-field pattern requirements.
Shaping® consists of two software packages, one for antenna design, another for antenna simulation.
- Antenna Design Package
The antenna design package provides exact, closed-form solutions for surface profiles of reflectors fed by a single horn antenna. It serves as a powerful design tool for shaped reflector antennas responding to arbitrary far-field pattern requirements. The solution is direct and exact, with no optimization algorithms or recursive iteration schemes involved. The software tool generates hundreds of reflector surface grid point data per minute of real time on a laptop PC.
- Antenna Simulation Package
The antenna simulation package provides effective electromagnetic analysis simulations for reflector antennas. The surface of the reflectors can be of arbitrary geometry, and the simulation tool generates accurate electromagnetic fields in both near and far regions.
Examples of Shaping® for the Design of Contour Beam Antennas
Three shaped reflectors, each with a single feed, provide beam coverage following both border and coastline of the continental USA, Latin America, and China respectively.
