Amazon workers are known as Amazonians, but recent reports of dire working conditions at all levels of the company destabilize the idea that employees are treated as warriors and giants. And there’s more skepticism when that renaming comes without any meaningful change in corporate values or priorities. As just a job, a paycheck to take care of the bills!” Noreen Malone wrote in The New York Times.Ĭorporate nicknames like Metamates don’t have the same impact when employees view themselves as just workers. ”If the tight labor market is giving low-wage workers a taste of upward mobility, a lot of office workers (or “office,” these days) seem to be thinking about our jobs more like the way many working-class people have forever. This idea is seen as more and more antiquated. mn mn Gm Gn Gn ( 6.9.7.2 ) 012 C66 ik2 + G A n + ik1 + GB ik + G + x m mn mn G G G G m n m n ( 6.9.7.3 ) ij Metamaterial is periodic and thus. There’s been a tidal wave of cultural cynicism lately pushing back against the idea that a job needs to provide people with more than just a paycheck - that workers must want a purpose. We intend for this to generalize the method developed by POEMS for a planar interface and to develop a method of numerical homogenization.To be clear that’s Ship > Shipmates > Self Right? So Meta > Metamates > Me Or Company > Co-workers > Employee?- Paul Lomax February 15, 2022 These models will be validated by numerical simulations that take into account the microstructure of the metamaterial by exploiting the periodicity of the medium.

In the continuation of the work of the University of Toulon in homogenization and of other partners in the field of asymptotic methods, we will try to correct the existing models to extend their range of validity.

In the continuation of the work already done by POEMS, we will precise the range of validity of the simpler homogenized model, in frequency and time domains, both theoretically and numerically. We will combine three types of approaches: With this ANR project, our ambition is to contribute to the development of models for metamaterials that are both physically relevant and accessible to numerical computation. Surprising phenomena also occur for other contrasts when the interface is not smooth. Thus, when considering an interface between a dielectric and a metamaterial, with a permittivity and / or permeability contrast equal to -1, it appears an accumulation of energy at the interface that is not compatible with the usual mathematical/physical framework. There are even simple configurations such that the model in the frequency domain is clearly not correct. However, when the dissipation in the metamaterial is negligible (which is desired for applications), the homogenized model is not standard (the dielectric permittivity and magnetic permeability are assumed to be real negative in a certain range of frequencies) and the use of conventional numerical methods is not obvious. This approach is now widely used by physicists and is the subject of an active mathematical research in the community of homogenization. An attractive alternative is to model the metamaterial by a homogeneous material, with physical constants of negative real part. Yet it is not conceivable to simulate these materials in all their complexity. The optimization of devices using metamaterials requires the development of appropriate simulation tools. ) and thus arouse great interest in many potential applications (super lenses, stealth coatings, miniaturization of antennas etc.). These 'metamaterials,' which have a complex multiscale structure, lead to extraordinary phenomena as regards the propagation of electromagnetic waves (negative refraction, 'sub wavelength' resonance cavities etc. Recent discoveries have shown the feasibility of weakly dissipative electromagnetic materials, whose effective dielectric and magnetic constants have negative real parts.
