Design, simulation and fabrication of a new terahertz cross-shaped metamaterial bandpass filter to obtain a narrow frequency bandwidth

Design and Fabrication of a Narrow-bandwidth Micromechanical Ring Filter using a Novel Process in UV-LIGA Technology

This paper presents the design and a new low-cost process for fabrication of a second-order micromechanical filter using UV-LIGA technology. The micromechanical filter consists of two identical bulk-mode ring resonators, mechanically coupled by a flexural-mode beam. A new lumped modeling approach is presented for the bulk-mode ring resonators and filter. The validity of the analytical derivatio...

Narrow bandpass filters (NBPF) are an important type of thin film filter technology that have become commonplace within the electrooptics industry. These devices are indispensable in fields such as analytical instrumentation, microscopy and telecommunications. NBPF are typically characterized as having high transmission with steep roll-offs and broad isolation. Thin film coating designs that me...

Metamaterial composite bandpass filter with an ultra-broadband rejection bandwidth of up to 240 terahertz

Achievement of arbitrary bandwidth of a narrow bandpass filter.

By adjusting the coating parameters to vary the refractive index of the thin film material, we are able to fine tune the bandwidth of a narrow bandpass filter to an arbitrary value. The relation between the varied index Deltan and the maximum arbitrary bandwidth was analyzed. A 4-skip-0 bandpass filter for a 100 GHz DWDM system was designed and fabricated. In addition, the relation between the ...

Design and Simulation of a Clamped-Clamped Micromechanical Beam AM Frequency Mixer-Filter

In the last decade Micromechanical components for communication applications has been fabricated via IC-compatible MEMS technologies. In fact, its most important impact is not at the component level, but rather at the system level, by offering alternative transceiver architectures that reduce power consumption and enhance performance. In this paper a mixer-filter for AM frequency receiver with ...
