Attenuation of Several Common Building Materials in Millimeter-Wave Frequency Bands: 28, 73 and 91 GHz
Nozhan Hosseini, Mahfuza Khatun, Changyu Guo +5
Future cellular systems will make use of millimeter wave (mmWave) frequency bands. Many users in these bands are located indoors, i.e., inside buildings, homes, and offices. Typica…
Indoor and Outdoor Penetration Loss Measurements at 73 and 81 GHz
Mahfuza Khatun, Changyu Guo, David Matolak +1
In this paper, we present millimeter-wave (mmWave) penetration loss measurements and analysis at E-bands-73 GHz and 81 GHz. Penetration loss was measured for common building materi…
Millimeter-Wave Path Loss at 73 GHz in Indoor and Outdoor Airport Environments
Mahfuza Khatun, Changyu Guo, Letizia Moro +2
In this paper, two large-scale fading path loss models are presented based on indoor and outdoor channel measurements at 73 GHz. The line-of-sight millimeter-wave propagation measu…
Mappings of finite distortion: Formation of exponential cusp
Changyu Guo
We consider a quasi-convex planar domain Ωwith a rectifiable boundary containing an exponential cusp and show that there is no homeomorphism f: \bR^2\to\bR^2 of finite distortion w…
