Rectangular horn is one of the simplest and most widely used microwave antennas. In this paper, an electromagnetic simulator, WIPL-D is used to analyze and optimize the dimensions of the horn antenna ...
Assistant Professor of Astrophysics Meredith MacGregor and NIST Physicist Jake Connors taught their graduate students how to build and use radio horn antennas to locate neutral hydrogen in space.
The systematic framework for the proposed multi-liquid identification is depicted in Fig. 1. The system comprises a space-time-coding metasurface illuminated by a feeding pyramidal horn antenna, a ...
