What is it about?
Metamaterials or artificial media have several special properties concerning electromagnetic waves. They demonstrate remarkable functional performance in various fields, including the absorption, emission, sensing, transmission, and guiding of light, sound, energy, heat, friction, strength, and electric energy. Their unique properties have captivated scientists looking to address issues in antennas and microwave circuits. MTM’s are composite structures called cells artificially arranged and embedded in a base medium, generally of the dielectric substrate. Cells' special geometries let metamaterials show contradictory electromagnetic characteristics, which makes them quite attractive for use in technology. It is feasible to control the permittivity and permeability by changing parameters like cell size, shape, and arrangement to attain planned properties. These characteristics mainly consist of homogeneity since the cells are much smaller than the operational wavelength, guaranteeing constant performance over several frequencies

Why is it important?
Metamaterials are important because they provide unprecedented control over electromagnetic behavior, unlocking new possibilities in communication, sensing, energy, and defense.
Perspectives
From my perspective, this publication provides a timely and innovative contribution to the field of electromagnetic materials and their application in modern communication systems. The exploration of metamaterials not only demonstrates their theoretical potential but also shows practical promise for improving antenna performance in high-frequency bands, such as those used in 5G and beyond. As a researcher in this area, I particularly appreciate the clear methodology and the relevance of the results for future antenna miniaturization and reconfigurability, which are crucial for next-generation wireless systems.
