An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

This study demonstrates a label‐free optical method to monitor cells using a terahertz metasurface‐based biosensing platform. The obtained terahertz signal change for the cell‐contained nanoslots before and after external stimulus is analyzed in terms of transmittance and frequency shift, dynamically representing the cell apoptosis process.

This work introduces a low‐loss diffractive neural network, fabricated using an imprinting technique with parowax material, for recognizing and manipulating the topological charge of orbital angular momentum (OAM) waves. It is also demonstrated that the low‐loss diffractive network can perform mathematical operations based on the topological charges of

Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

In vivo Terahertz Sensing of Skin Cancer Patients
This study presents the first in vivo measurements of skin cancer patients in a hospital setting using a handheld THz probe. Furthermore, a new analysis approach is developed to generate a patient‐normalized THz response function, which enables clear contrast to be seen between cancer and healthy skin of the same patient.The first in vivo study of skin
