calledleft-handed metamaterials(LHM): a left-hand rule instead of the usual right-hand rule delivers the direction of the Poynting vector fromEandB. The term “left-handed” is somewhat unfortunate as it may suggest a (non-existing) relation to the phenomenon of chirality, as discussed below...
Dynamic loads of considerable duration are known to cause more significant damage to structures compared to static loads. Dynamic pulse loads can degrade material properties in structural elements that might otherwise withstand static loads of the same magnitude. This is primarily due to the dynamic lo...
Controlling the thermal expansion of materials is of great technological importance. Uncontrolled thermal expansion can lead to failure or irreversible destruction of structures and devices. In ordinary crystals, thermal expansion is governed by the asym
Besides, some harmon- ics exist in the array due to the mutual coupling effects and construction of the unit cell's asymmetric pattern. The absorber's frequency selectivity is achieved as it provides a narrow bandwidth with a high absorption level in five selected frequencies of 3.80 GHz, ...
Negative refractive index due to chirality is obtained in the near infrared range of the spectrum for either left or right polarization.doi:10.1016/j.optcom.2013.10.070Giloan, M.Astilean, S.Elsevier B.V.Optics CommunicationsGiloan, M., Astilean, S.: Negative index optical chiral metamaterial...
In addition, the suggested structure gives high negative refractive index due to the large chirality in order to obtain an efficient polarization converter. We also present a numerical analysis in order to show the additional features of the proposed chiral MTM in detail. Therefore, a MTM sensor ...
To be specific, the rotation angle per wavelength in our design is as large as 3400°/, implying that the chirality is significantly stronger than any other planar CMMs reported previously. Due to the giant chirality, the negative refractive index is achieved for circularly polarized waves....
This paper presents a algebraic analysis of electromagnetic chirality-induced negative refractive index in a four-level atomic medium. According to analyze mathematically its argument of the complex refractive index for one circular polarization, it found that the negative refractive index without ...
Large and tunable negative refractive index (NRI) via electromagnetically induced chirality is demonstrated in a semiconductor quantum wells (SQWs) nanostructure by using the reported experimental parameters in J.F. Dynes et al., Phys. Rev. Lett. 94 , 157403 (2005). It is found: the large ...
