Low insertion loss, graphene-based platform for loss modulation

Conference on Lasers and Electro-Optics, 2022
We show low insertion loss platform based on loss modulation of hybrid SiN/graphene structure. We measure an intrinsic quality factor of 80,000 in a ring resonator based device when the graphene is in its high loss state.

On windscreen insertion loss

The Journal of the Acoustical Society of America, 2002
Microphone windscreens are used to attenuate wind noise. They add impedance between the source and microphone, not accounted for when the system is checked by acoustical calibrator or when used in the field. The procedure for the characterization of the attenuation has recently been addressed in ANSI S1.17/2000 part 1.

Insertion loss of an acoustic enclosure

The Journal of the Acoustical Society of America, 2004
Acoustical enclosures are the common arrangements in reducing airborne noise from shipboard machinery such as engines and generators. In this paper the theoretical models, established based on statistical energy analysis, are presented for predicting the insertion loss of acoustical enclosures in different frequency ranges.
