Research on a Drone‐Based Vacant Parking Detection System

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 6, Page 851-857, June 2026.
It can be difficult to know which spaces are available in parking lots and bicycle parking areas, so knowing the availability status is necessary for efficient parking. Therefore, in this study, we developed the drone that can display the availability status. Availability is determined by whether it can read a QR code attached to the ground. To conduct

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Dispersion‐Engineered Broadband Transparent Meta‐Cloak

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Achieving broadband performance remains a critical challenge in engineering physics. Here, theoretical derivation shows that the core phase compensation conditions for broadband transparent cloaking exhibit dispersive characteristics. A novel broadband transparent cloaking paradigm via dispersion engineering is proposed, and a meta‐cloak that realizes ...

Noninvasive Promotion of Neuronal Differentiation in Human Neural Progenitor Cells Using Terahertz Wave Illumination

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
Terahertz (THz) waves provide a nonionizing and noninvasive approach to regulate neuronal differentiation by resonantly interacting with biomolecular vibrational modes. THz irradiation regulates gene expression and intracellular signaling pathways, enhancing neuronal marker expression and promoting neurite outgrowth. This biophysical modulation enables
