By deducing the effective thermal conductivities of rotating objects, we propose an adaptive thermal cloaking metadevice that is composed by three rotating layers with different roles. The joint effect of three rotating layers makes the effective thermal conductivity a real number on the reciprocity ...
thermal emitters narrowband refractory mid-wave infrared inverse design optical gas sensing Introduction Thermal emitters have been widely used in a variety of applications, ranging from lighting to imaging and sensing, and conventionally emit light over a broadband wavelength and a wide angle range.

We demonstrate a multi-fidelity (MF) machine learning ensemble framework for the inverse design of photonic surfaces, trained on a dataset of 11,759 samples that we fabricate using high throughput femtosecond laser processing. The MF ensemble combines an
Switching functionality is pivotal in advancing communication systems, serving as a paramount mechanism. Despite numerous innovations in this field, optical switch design, fabrication, and characterization have traditionally followed an iterative approach. Within this paradigm, the designer formulates an infor...
Applying intelligence algorithms to conceive nanoscale meta-devices becomes a flourishing and extremely active scientific topic over the past few years. Inverse design of functional nanostructures is at the heart of this topic, in which artificial intell
Combining the electric fields in the device from adjoint simulations with those from the expected illumination, in this case broadband linearly polarized plane waves, the gradient is computed in a fixed number of simulations independent of the num- ber of design voxels. Fabrication constraints were ...

Researchers have also extensively explored the design of 3D unit structures. An et al. deduced the amplitude and phase response of a 3D all-dielectric atom and executed the inverse design based on the forward design [110]. This method resulted in the design of a meta-filter design network, ...

Sometimes, additional efforts are required to derive the sensitivity analysis if unusual objectives or constraints are incorporated into the optimization formulation even though the existing gradient-based scheme has been used in device design. Another important challenge is that, up to now, most of ...
