ON-CHIP WAVEGUIDE DIGITAL METALENSES VIA INVERSE DESIGN

On-chip waveguide digital metalenses via inverse design

Given the recent success of metasurfaces in free-space applications, these concepts can be leveraged to an even larger extent in on-chip waveguide systems.The in-plane diffractive metasurfaces enable the manipulation of guiding waves in the multimode regime with greater parallelism than conventional single-mode or few-mode waveguides, leading to ex

High Sensitivity of the Tiger Beetle, Cicindela circumpicta, to Toxicity from Pyrethroids and Neonicotinoids, and Implications for Ecosystem Function and Species Extinctions

Risks to non-target species from pesticides have been a concern since the 1960s, but non-target arthropods have never received the attention as have non-target vertebrate species.Pesticide exposure could be a contributing factor in the decline ESTROSMART of the endangered Cicindela nevadica lincolniana, as well as declines in predaceous and pollina
