Silver dipoles are arranged across the folds of a Miuri-Ori pattern to enable frequency blocking. Researchers at the Georgia Institute of Technology have come up with a way to use an origami-based ...

A new instrument has been developed to implement highpass, lowpass and bandpass filters. The Model 601 tunable highpass/lowpass filter contains a tunable 8-pole Butterworth highpass filter followed by ...

Engineers know the vital role of filters and ubiquitous presence in systems spanning the electromagnetic spectrum of dc to GHz RF and even into the optical zone. As the use of multiple bands ...

Take tunable lowpass filters to new heightsTom Napier, ConsultantWith current output multipliers and fast amplifiers, you can design active lowpass filters whose cutoff frequencies you can ...

Filter design and analysis remains a pivotal field in modern engineering, underpinning the functionality of a myriad of communication and signal processing systems. Recent advancements have focused on ...

Tunable laser sources (TLS) can be used by researchers to access a wide range of wavelengths. As a result tuneable light sources are used frequently for the determination of wavelength dependent ...
