A review of metal mesh filters

SPIE Proceedings, 2006
The Astronomical Instrumentation Group at Cardiff University has been developing metal mesh optical filters for more than 30 years, which are currently in use in many ground-, balloon- and space-based instruments. Here we review the current state of the art with respect to these quasi-optical components (low-pass, high-pass and band-pass filters ...

Reinforcement of Bone Cement Using Metal Meshes

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1989
Following on from previous work reported in this journal, a practical system has been developed for in situ fibre reinforcement of bone cement in the hip joint prosthesis. A fibre preform is inserted during the operation, surrounding the metal stem of the prosthesis, forming a composite with the cement. Tests performed on full-scale models of the joint

Metal mesh for sustainable fish

Filtration + Separation, 2020
A Swiss salmon breeder is using the Recirculating Aquaculture System (RAS) 2020 with GKD’s stainless steel Porometric mesh. The metal mesh is used in the drum filters for mechanical water cleaning, offering high levels of flow rate and cleaning.

Metal mesh resonant filters for terahertz frequencies

Applied Optics, 2008
The interest in terahertz photometric and imaging measurements has motivated the development of bandpass resonant filters to be coupled to multiple-pixel devices such as bolometer arrays. Resonant grids are relatively simple to fabricate, exhibiting high transmission at the central frequency, a narrow bandpass, and good rejection of the side ...

Microstructure technology for fabrication of metal-mesh grids

Applied Optics, 1994
Motivated by the need for highly efficient far-IR Fabry-Perot étalons for airborne and space astronomy, we have developed a high-yield photolithographic technique for producing low-loss metal-mesh reflectors. We describe the production technique and report on the mesh flatness and uniformity.

Effects of mesh voids on insertion loss of metallic mesh coatings

SPIE Proceedings, 2007
Metallic mesh thin-film coatings have been used for many years to provide electromagnetic interference (EMI) shielding on infrared windows and domes. During the fabrication of these conductive, micron-sized mesh patterns, mesh voids or holes in the mesh pattern occasionally occur.

Metal Mesh Interference Filters for the Far Infrared

Applied Optics, 1967
Far ir Fabry-Perot type interference filters consisting of two parallel, closely spaced metal meshes have been reported by others. Using improved techniques, filters of this type have been fabricated with larger finesse and peak transmittance. Measured transmittance curves, obtained with the Aerospace lamellar grating interferometer have led to ...

Inductive cross-shaped metal meshes and dielectrics

Applied Optics, 2002
The Micro-Stripes program has been used to calculate resonance wavelengths and the bandwidth of inductive cross-shaped metal meshes in contact with dielectric layers. The shift of the resonance wavelength, depending on the thickness of the dielectric layers, has been studied for two refractive indices.

A nanobursa mesh: a graded electrospun nanofiber mesh with metal nanoparticles on carbon nanotubes

Nanoscale, 2014
A new material, nanobursa, consisting of polymeric nanofibers encapsulating carbon nanotubes (CNTs), carrying myriad types of metallic nanoinclusions, and suitable for functional grading, is introduced.

Metal mesh filters for THz applications

2007 Joint 32nd International Conference on Infrared and Millimeter Waves and the 15th International Conference on Terahertz Electronics, 2007
The Astronomy Instrumentation Group at Cardiff University has been developing metal mesh optical filters for more than 30 years. They are currently in use in ground-, balloon- and space-based astronomical instruments and in many laboratory-based THz applications.
