| The Very First Ever Made 3D/4D Virtual Laboratory for Antennas |
| N. I. Yannopoulou, P. E. Zimourtopoulos |
| ABSTRACT |
| Based on the experience we have gained so far, as independent reviewers, we thought that may be proved useful to publicly share with the interested author, especially the young one, some practical implementations of our ideas for the interactive representation of data using 3D/4D movement and animation, in an attempt to motivate and support him in the development of similar dynamic presentations, when he is looking for a way to locate the stronger aspects of his research results in order to prepare a clear, most appropriate for publication, static presentation figure. For this purpose, we selected to demonstrate a number of presentations, from the simplest to the most complicated, concerning well-known antenna issues with rather hard to imagine details, as it happens perhaps in cases involving Spherical Coordinates and Polarization, which we created to enrich the very first ever made Virtual Laboratories of Antennas, that we distribute over the Open Internet through our website Virtual Antennas. These presentations were developed in a general way, without using antenna simulators, to handle output text and image data from third-party CAS Computer Algebra Systems, such as the Mathematica commercial software we use or the Maxima FLOSS we track its evolution. |

| Near-field Method in Solving Inverse Scattering Problem of Spherical Electromagnetic Waves in Chiral media |
| N. M. Berketis |
| ABSTRACT |
| We have developed two methods to study an inverse scattering problem of electromagnetic waves in chiral media, for a spherical scatterer perfect conductor. The first called Far-field inverse problem was described analytical in our previous work. The second called Near-field method is given in detail in the present paper. It is a geometrical method based on the scattered fields. Using Near-field experiments, in which the scattered field is measured at the source, we solve the corresponding inverse scattering problem that is to determine the coordinates of the center and the radius of the spherical scatterer. |
