Special Issue Information

Dear Colleagues,

Researchers have taken an interest in the design of MTM-based sensors due to their unique electromagnetic properties, which enable them to detect anomalous changes with sensitivity and precision. Using computational and experimental tools, the need for high-performance sensor characterization for healthcare monitoring is crucial for creating a better and more sustainable future for everyone.

This Special Issue aims to explore recent advances and developments in high-performance metamaterial sensor technologies and methods applicable to healthcare monitoring systems. It lays the groundwork for designing a new class of metamaterial-based sensors that can improve the sensitivity of sensors. It aims to cover recent theoretical and experimental accomplishments in piezoelectric and electromagnetic as well as other novel or combinational concepts. The sensitivity of wearable and flexible sensors at various sizes and for various fabrication materials and characteristics can also be addressed. Researchers are encouraged to submit original research, letters, and reviews.

Tunable/switchable devices are more and more required in modern communication systems. However, the realization of the tuning requires the presence of active devices, which in turn must be biased. The current paper comes up with a solution for designing and experimentally validating such a switchable Frequency Selective Surface. Two different metallic structures are simulated and measured, having incorporated the same topology control network (CN). In this scenario, the main innovation of this paper is the presence of the feeding part, namely the control network. In this work, the main FSS structure is flanked by three parallel CN microstrip lines and several via holes that allow biasing the active elements, namely PIN diodes. The switchability of the proposed structure is achieved through PIN diodes, whose bias determines the values of the elements in the equivalent circuit. At different biases, the response of the FSS changes accordingly. From all possible values of the bias, the extreme cases when the diodes act as (almost) short- and open-circuits are considered in the submitted manuscript for the sake of brevity. These cases are modeled by the main and cut-slot structures, respectively. The proposed structures have been evaluated using electromagnetic simulation and implemented on an FR4 substrate having a thickness of 1.58 mm. With the periodicity of the square-shaped unit cell of 18 mm edge length, different filtering bands are obtained below 12 GHz. Another novelty that has received very little consideration in the existing literature is the use of a finite array of unit cells instead of an infinite one. And finally, tests in an anechoic chamber have proved that there is a good agreement between practical and simulation results and also demonstrated the proper performance of the devices for wide angular incidence for both TE and TM polarizations.
