Tunable Filters with Extended Tunability
Japanese Journal of Applied Physics, 1992Filters with extended tunability using waveguide devices are proposed. The first and second types of filters are combinations of a filter with a wide tuning range and a filter with narrow passbands. The first type is composed of cascaded filters and the second type is the filter with a wide tuning range embedded in a resonator.

Tunable FBARs: Intrinsic vs. extrinsic tunability
2012 IEEE/MTT-S International Microwave Symposium Digest, 2012The methods used to make the Film Bulk Acoustic Resonators (FBAR) tunable is reviewed. Intrinsically tunable FBARs make use ferroelectrics in ferroelectric and paraelectric (non-polar) phases have tunabilities up to 5% and more. Extrinsically tunable resonators are based on traditional piezoelectric FBARs and make use of external varactors and ...

Tunable acoustic metasurface based on tunable piezoelectric composite structure
The Journal of the Acoustical Society of America, 2022Due to the potential engineering needs, the passive tunable metasurfaces with a high performance equivalent to the active phased array is worthy of research. Here, a passive ultrathin metasurface unit composed of a piezoelectric composite structure (PCS) connected to an external capacitor, which can modulate the phase of the transmitted acoustic waves ...

Optics Letters, 2016
We report the demonstration of a tunable dysprosium laser. The experiment employed in-band pumping of a Dy3+-doped fluoride fiber and a simple resonator design involving a ruled diffraction grating. The laser produced tuning between 2.95 and 3.35 μm, limited by the availability of optics.

Analytical Chemistry, 2010
We have developed a resistance-based chemical sensor (chemiresistor) for volatile organic compounds whose sensitivity can be reversibly increased over a range of nearly 2 decades by the application of tensile strain. This polymer-based sensor is comprised of Au-plated magnetic particles structured into conducting chains by the application of a magnetic

Most current radio receivers use SAW bandpass filters for band selection. Their center frequency depends on the dimensions of the interdigital structure. Therefore, in the next few years, SAW technology will face some fabrication process limits because of the need of higher operating frequencies. BAW resonators are emerging as an alternative technology.

Tunable Aeroelasticity With Self-Tunable Composite Materials
AIAA SCITECH 2024 ForumThis paper reports the dynamic performance of novel aerospace structures with embedded multiphase materials with tunable stiffness and damping parameters. The proposed structures embedded multiphase materials exploit the thermal loads generated in high-speed fights to tune the stiffness and damping parameters, and thus, enable adaptive aeroelastic ...
