“…Such an approach is clearly applicable to only aperture antennas, since the radiated and captured field can interact directly with the modulated particle. However, the concept of metamaterial-based nonreciprocity can be extended to any antenna system if a proper space-time varying (STV) cover is designed around it, as proposed in [107]- [110].…”

The development of the next generation of wireless systems is bringing renewed attention to the physical layer of the communication link. Indeed, the new low-latency requirements cannot be satisfied relying only upon the extreme virtualization of the hardware functions. Moreover, conventional wireless systems with fixed characteristics and functionalities are not appropriate to modern electromagnetic environments, which undergo continuous and fast variations. Embedded smartness is a required feature for widening the range of the possible electromagnetic responses to support advanced and novel functionalities. In this paper, we show how the combination of 2D metastructures with conventional antennas and reflectors enables an unprecedented electromagnetic behaviour, which is at the basis of new properties, capabilities, and applications. In particular, we propose an emerging design approach based on the shifting of the reconfigurability, adaptivity, sensing, and power management of a wireless system at the physical level, thanks to the use of properly designed 2D metastructures to be coupled with standard antennas and reflectors.

“…Absorbers: A Metamaterial absorber is intended to efficiently absorb electromagnetic radiation such as light. structure is designed to broaden the bandwidth of metamaterial absorber composed of a patterned square metallic patch and a metallic ground plane separated by a dielectric layer [6]. The conductivity of the metal and the thickness of the dielectric layer determine the bandwidth of the metamaterial absorber [7].…”

This paper presents a design of measuring system with Metamaterial inspired CSRR (Complimentary SplitRing Resonator). The device is of portable, cost effective and which gives the accuracy. The theoretical approach of Metamaterial with its different applications is also discussed here. This paper is of high significance as current testing equipment of micro Complimentary Split-Ring Resonators (CSRR) are highly expensive, and therefore rare, but are also extremely bulky. Therefore developing portable, cost-effective, and robust testing equipment operating within the internationally reserved ISM radio frequency band is a main research work.

Microwave waveguides allow an effective transfer of electromagnetic energy through straight connection or well-rounded curves, but become rather inefficient in case of sharp bends or squeezed waveguide cross-sections. Here, we discuss the possibility to funnel the electromagnetic energy propagating in a waveguide through arbitrarily curved narrow channels hosting a metamaterial-inspired structure able to convert the propagating mode of the waveguide in an electric signal, and vice versa. We show experimentally how sharp bends can be inserted within these propagation channels of arbitrary lengths without introducing significant insertion losses. In particular, efficient energy funneling in 90°-, 180°-, and “S”-shaped bends are numerically and experimentally verified. The proposed reflectionless waveguide bends may find applications in modern radar and antenna systems, where the demand for space and weight reduction of the electromagnetic circuitry is ever growing
