Programmable Anisotropic Terahertz Permittivity via High‐Aspect‐Ratio 3D‐Printed Dielectric Mesh Networks

Advanced Optical Materials, EarlyView.
A 3D‐printed Terahertz (THz) anisotropic dielectric with programmable permittivity by varying infill density and creating high‐aspect‐ratio channels is presented. The proposed design was evaluated both experimentally, through THz time‐domain spectroscopy, and theoretically, through FDTD simulations and Effective Medium Theory analysis.

Determination of the Complex Permittivity of Dispersive Materials Without Assuming a Dielectric Relaxation Model

, 2010
This paper presents a procedure to extract the complex relative permittivity of a dispersive material without assuming a dielectric relaxation model. To assess and validate the procedure, published experimental data for methanol were considered.

Nanomaterial‐Incorporated Nonlinear Optical Waveguides Explored With All‐Fiber Multiphoton Polymerization

Advanced Optical Materials, EarlyView.
Nonlinear waveguides are fabricated via an all‐fiber‐based multiphoton polymerization approach incorporating upconversion nanoparticles (UCNPs), which enable both multiphoton absorption at telecommunication wavelengths and nonlinear saturable absorption operation.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
