Metamaterials at terahertz frequencies offer unique opportunities, but are challenging to fabricate in bulk. We adapt the fabrication procedure for microstructured polymer optical fibers to inexpensively fabricate metamaterials potentially on an industrial scale. We produce polymethylmethacrylate fibers containing ~10 μm diameter indium wires separated by ~100 μm, which exhibit a terahertz plasmonic response.

To investigate simple fabrication approaches for multiple assay needs, we created a fluid-absorbing channel system made of cotton material. This device was used to establish a multiple detection platform, and solve contamination issues that commonly affect lateral flow-based biomedical devices, for clinical urinalysis of nitrite, total protein, and urobilinogen.

Solvent bonding is a simple and versatile method for fabricating thermoplastic microfluidic devices with high quality bonds. We describe a protocol to achieve strong, optically clear bonds in PMMA and COP microfluidic devices that preserve microfeature details, by a judicious combination of pressure, temperature, an appropriate solvent, and device geometry.
FAQs
Performance depends on how unit-cell dimensions, spacing, and composition shape the collective response rather than on the bulk material alone. These parameters can shift a device toward a targeted resonance, impedance, or wavefront behavior. Consequently, fabrication converts a designed geometry into a measurable physical response, making dimensional control central to whether the intended effect appears.
Subwavelength unit cells allow individually patterned elements to contribute to a coordinated collective response. Their arrangement provides control over how electromagnetic, acoustic, or mechanical waves interact with the structure. Changing the size, spacing, or composition of these cells therefore changes the device-level behavior, allowing fabrication choices to support tailored wave manipulation rather than an uncontrolled material response.
Fabrication quality determines how closely the produced structure matches its intended geometry. Deviations in dimensions, spacing, or composition can change the collective response and prevent the device from reaching its designed resonance, impedance, or wavefront behavior. In physics research, precise pattern formation is therefore essential for connecting the predicted function of a device with its realized performance.
A typical workflow selects a material system, deposits or forms the required material, and defines the pattern using lithography, etching, or additive manufacturing. The process then builds an ordered arrangement of unit cells with specified dimensions and spacing. The chosen route depends on whether the target structure is produced through layered fabrication, pattern removal, or direct three-dimensional construction.
These methods support several device classes, including absorbers, antennas, lenses, sensors, and optical or acoustic cloaking structures. Their functions depend on the engineered geometry and resulting response, such as controlling absorption, wave propagation, or wavefront shape. This range makes fabrication relevant to both compact components and larger structures designed for specialized electromagnetic or acoustic behavior.
Advances in nanoscale and three-dimensional manufacturing expand the geometries that can be realized beyond simpler patterned structures. That broader fabrication capability supports continued development of metamaterial devices for research and technological applications, including structures designed to control electromagnetic, acoustic, or mechanical behavior. In physics, these advances help translate engineered wave responses into increasingly practical device forms.
