Special Issue Information

Dear Colleagues,

It is my great pleasure to announce this Special Issue on the Theory, Methods and Applications of Electromagnetic Scattering. Modern telecommunication systems, radio links, monitoring systems, environmental sensors, radars, and mobile devices must all operate in complex scenarios where knowledge of electromagnetic propagation and scattering phenomena is mandatory for their function in different complex environments or to acquire different environmental physical parameters. Moreover, new biomedical systems aimed at acquiring and monitoring biological parameters offer different services that expect a high degree of knowledge in terms of interaction and electromagnetic propagation.

These systems must be integrated into the new generation of communication devices able to offer, in addition to the usual standard services of previous systems, ultra-broadband internet connection, IP telephony, mobile web access, data postprocessing, data storage, and other interesting applications (such as the use of artificial intelligence (AI) to manage and process data). At the same time, they should not produce electromagnetic compatibility problems. In such a framework, the study of electromagnetic propagation and scattering in complex scenarios is mandatory for the development of modern systems that make use of electromagnetic waves for the detection and direct and indirect measure of suitable environmental and biological physical quantities.

In this framework, the use of microwave bands is mandatory to dramatically improve the performance of these systems. These device types are commonly used in several fields of application such as environmental and structural engineering monitoring, precision agriculture, pollution monitoring, inverse or direct scattering, and other practical and interesting applications. The objective of this Special Issue is to provide an overview of the current research on electromagnetic propagation and scattering, highlight the latest developments and innovations, and identify new challenges and opportunities of applications.

This Special Issue welcomes original research articles and reviews. Research areas may include (but are not limited to) the following:

  1. Inverse microwave imaging applications.
  2. Microwave tomograpy for stroke and early tumor detection (brain and breast).
  3. Measurement systems and dosimeters.
  4. Antenna design.
  5. Electromagnetic propagation in complex media.
  6. Electromagnetic propagation in plasma.
  7. Underwater and underground electromagnetic propagation.
  8. Landsmine detection systems.
  9. Lifesignal detection systems.
  10. Industrial NDE/NDT.

I look forward to receiving your contributions.

This work presents a methodology for designing deployable reflector antennas that combine origami structures and the Fresnel zone plate lens to obtain a compact antenna structure. In particular, Miura and Yoshimura’s origami patterns have been considered for the design of the Fresnel reflector mirror and the conical horn antenna feeder, respectively. A set of memory-form alloy (MFA) actuators have been used to deploy the antenna. The MFA actuators are activated by a direct current aimed at increasing the temperature and activating the memorized shape. The combination of these techniques provides light, inexpensive, and very compact antennas, particularly suitable for satellite applications. A numerical and experimental assessment campaign has been carried out on antenna prototypes operating in the Ku band at 15 GHz. The obtained experimental results are quite promising. Full article
