2. Domestic activities related to areas covered by Commission D
Technical Committee on Microwave Photonics (IEICE)
Following technical meeting was held on May 11, 2017 (Tokyo). Three invited talks were presented, that were entitledon “Current Status and Perspective of R&D in High Capacity FWS using Microwave and Millimeter-wave”,“VHF-band Broadband Fixed Wireless systems to Resolve Digital Divides," and "Optical and Radio Converged AccessNetwork for Accommodating Mobile Services in Beyond-5G Era”. Several regular contributions were also presented
related to 60 GHz band Radio-over-Fiber System, systems and functional devices for FM-CW Linear Cell Radar,millimeter-wave mobile terminal localization in 5G mobile, photonic based millimeter-wave radio link. The committee
chair, Prof. Yuich Kado, Kyoto Inst. of Tech. and the vice-chair, Prof. Hiroyuki Toda, Doshisha Univ., are members onJapan Commission D.
Another meeting was held on July 20-21, 2016 (Obihiro). (jointly held with related technical committees referring tolight-wave and radio-wave workshop). Four invited talks were presented, that were entitled on “Application of RoF
technique in V/UHF band and some problems for next generation wireless communications”, “Layer2 technologies in
Optical Wireless Convergence Platform for IoT Services", “Precision Inspection of Dielectric Constant Measurement
Using Terahertz Time-domain Spectroscopy System and Its Application”, and “Scattering and Guiding Problem ofElectromagnetic Waves in Inhomogeneous Media by Improved Fourier series Expansion Method - The Application of
Photonic Crystal and Metamaterial -". Several papers related to following technical topics were presented:
heterogeneous wireless communication systems utilizing photonic technologies for 5G mobile systems, phased arraylaser system, optical frequency comb generation, RoF-based millimeter-wave radar system, millimeter and terahertz
wave integrated circuits, photonic technology for microwave and millimeter-wave heterogeneous network, etc. One ofmembers on Japan Commission D, Prof. Naoto Yoshimoto (Chitose Inst. of Science and Tech.) was contributed in theorganization.
