Survey of Millimeter-Wave Propagation Measurements and Models in Indoor Environments
Al-Samman, Ahmed; Cheffena, Michael (Peer reviewed; Journal article, 2021)The millimeter-wave (mmWave) is expected to deliver a huge bandwidth to address the future demands for higher data rate transmissions. However, one of the major challenges in the mmWave band is the increase in signal loss ... -
Template Imprinting Versus Porogen Imprinting of Small Molecules: A Review of Molecularly Imprinted Polymers in Gas Sensing
Cowen, Todd James; Cheffena, Michael (Peer reviewed; Journal article, 2022)The selective sensing of gaseous target molecules is a challenge to analytical chemistry. Selectivity may be achieved in liquids by several different methods, but many of these are not suitable for gas-phase analysis. In ... -
The Application of Lognormal Mixture Shadowing Model for B2B Channels
Cheffena, Michael; Mohamed, Marshed Kassim (Journal article; Peer reviewed, 2018)In this article, a Lognormal mixture shadowing model based on a cluster concept is utilized in the modeling of body-to-body (B2B) channels for different running and cycling activities. The mixture model addresses the ... -
Three-Site Diversity at Ka-Band Satellite Links in Norway: Gain, Fade Duration and the Impact of Switching Schemes
Rytír, Martin; Cheffena, Michael; Grotthing, Per Arne; Bråten, Lars Erling; Tjelta, Terje (Journal article; Peer reviewed, 2017)Analysis of two years of measurements from a three-site satellite beacon diversity experiment in Norway is presented. The operating frequency was 19.68 GHz, elevation angles were between 21.7° and 22°, and site separations ... -
Time-varying on-body wireless channel model during walking
Cheffena, Michael (Journal article; Peer reviewed, 2014)A novel dynamic channel model for on-body wireless communication during walking is proposed. The developed model utilizes a human walking model which provides detailed information on the movement of the human body parts. ... -
