Narrowband to Narrowband Frequency Tunable Slotted Dipole Antenna [PDF]

Journal of Physics: Conference Series, 2021
Abstract In this paper, the slotted dipole antenna structure is proposed to have four narrowband frequencies with ability to be reconfigured. Narrowband reconfiguration can be achieved by controlling the length of slotted dipole by using switches.

Narrowband Organic/Inorganic Hybrid Afterglow Materials

Molecules
Narrowband afterglow materials display interesting functions in high-quality anti-counterfeiting and multiplexed bioimaging. However, there is still a limited exploration of these afterglow materials, especially for those with a full width at half maxima

Switchable Broadband-to-Tunable Narrowband Magnetic Probe for Near-Field Measurements

Sensors, 2022
This paper presents a printed magnetic probe that can switch from broadband to tunable narrowband for near-field measurement. In the early design stage, we created a printed loop gap resonator as a magnetic reference sensor for the pre-compliance test in

Narrowband SIW-SSPP Hybrid Bandpass Filter With Compact Profile at Ka-Band

IEEE Access, 2023
In this paper, a narrowband bandpass filter comprising substrate integrated waveguide (SIW) and spoof surface plasmon polaritons (SSPPs) is proposed, achieving miniaturization and low insertion loss at Ka-band. SIWs and SSPPs exhibit low and high cut-off

Reed solomon inner-convolutional outer concatenated code with error-erasure decoding for narrowband and broadband power line communications [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2017
A novel concatenated coding system for both narrowband and broadband power line communications (NB-PLC and BB-PLC) is proposed. The order of the inner and the outer codes switches from the G3-PLC standard and the interleaver is eliminated.

Physics‐Based Narrowband Optical Parameters for Snow Albedo Simulation in Climate Models

Journal of Advances in Modeling Earth Systems, 2022
Accurate snow albedo simulation is a prerequisite for climate models to produce reliable climate prediction. Climate models would benefit from schemes of snowpack radiative transfer that are responsive to changing atmospheric conditions.

Narrowband-to-Broadband Conversions for Top-of-Atmosphere Reflectance from the Advanced Very High Resolution Radiometer (AVHRR)

Remote Sensing, 2020
The current lack of a long, 30+ year, global climate data record of reflected shortwave top-of-atmosphere (TOA) radiation could be tackled by relying on existing narrowband records from the Advanced Very High Resolution Radiometer (AVHRR) instruments ...

Comparison of predictions from a ray tracing microcellular model with narrowband measurements [PDF]

, 1997
In this paper predictions from a 3-D 'image-based' ray tracing model for microcellular environments are compared with three sets of narrowband measurements performed in a typical urban area. The comparisons illustrate that good agreement can be obtained,
