Journal of Polymer Science, Volume 63, Issue 21, Page 4394-4402, 1 November 2025.The use of SI‐PET‐RAFT has been gaining momentum for producing thick, homogenous, functional polymer brushes, in an oxygen‐tolerant manner. However, the connection between irradiation wavelength and the brush height has not been clear. Herein, we systematically explore the effect of irradiation wavelength on the resulting brush properties, finding a ...

Polarization division multiple access with polarization modulation for LOS wireless communications [PDF]
, 2011 In this paper, we discuss a potential multiple access and modulation scheme based on polarized states (PS) of electromagnetic (EM) waves for line-of-sight (LOS) communications. The proposed scheme is theoretic different from the existing polar modulation

Time-Hopping Multicarrier Code-Division Multiple-Access
, 2006 A time-hopping multicarrier code-division multiple-access (TH/MC-CDMA) scheme is proposed and investigated. In the proposed TH/MC-CDMA each information symbol is transmitted by a number of time-domain pulses with each time-domain pulse modulating a ...
