EDS-Soft Electrodynamic Systems is a scientific software company specializing in the mathematical modeling of antenna systems. They offer a range of products and publications related to antenna arrays and electrodynamic systems. Their software, such as the GuidesArray Rectangular program, allows users to execute mathematical modeling of phased antenna arrays created using rectangular waveguides. This software is particularly useful for designing complex directional antennas consisting of separate near-omnidirectional antennas positioned in space and driven by high-frequency signals. The mathematical models provided by EDS-Soft are based on electrodynamic solutions and boundary tasks, allowing for accurate simulations of infinite structures. The company's research focuses on the characteristics and interaction of radiators within phased arrays. They have developed efficient algorithms for calculating the characteristics of block phased arrays intended for scanning in limited angles and normal phased arrays with elementwise phasing. These algorithms take into account the influence of attenuators and consider interaction both in the outside space and power wiring circuits. In the field of publications, EDS-Soft has recently published a dissertation titled "Metal-Dielectric Structures in Antenna Arrays, Radio-Absorbing Coatings, and Near-Omnidirectional Radiators" authored by I. V. Sutyagin. This dissertation presents electrodynamic-level mathematical models for analyzing the radiation pattern characteristics of printed-circuit radiators within antenna arrays, including those located on finite screens of irregular shapes. Additionally, it introduces mathematical models for analyzing the characteristics of ultrawideband ribbon antenna arrays with wide-angle scanning. With their expertise in mathematical modeling and their dedication to research, EDS-Soft strives to provide advanced scientific software and contribute to the development of antenna systems and radiolocation technologies.
