TITLE:
Detection Probability of Foreign Object Debris using Radar Cross Section (RCS) Simulation for system performance analysis of Foreign Object Debris Detection System

ABSTRACT:
Since the accident at Charles de Gaulle Airport, research and development to electronically detect foreign object debris on the runway have been conducted. We are investigating the practical application of a system for detecting and recovering foreign objects debris on the runway by combining a 90 GHz millimeter-wave radar with a high-definition camera. After introducing the system configuration and describing the essential characteristics of the radar, we will present a demonstration system installed at Kuala Lumpur Airport in Malaysia. The relationship between RCS simulation and detection probability, which is necessary for the system performance, is also discussed, and the results are reported.

Semiconductor Nanostructures for Optoelectronics Applications

ABSTRACT:
Semiconductors have played an important role in the development of information and communications technology, solar cells, solid state lighting.  Nanowires are considered as building blocks for the next generation electronics and optoelectronics.  In this talk, I will present the results on optoelectronic devices such as lasers/LEDs, THz detectors, energy devices such as solar cells, photoelectrochemical (PEC) water splitting and Neuro-electrodes.  Future prospects of the semiconductor nanowires will be discussed.

Prospects for Radio-over-Fiber in Beyond 5G Mobile Access Networks

ABSTRACT:
Radio-over-Fiber has been adopted in Distributed Antenna Systems deployed by “neutral host” infrastructure providers for dense mobile user environments in city centres, shopping malls, transport hubs, stadia etc… However, mobile operators have been reluctant to use the technology directly in their mobile access networks, preferring to use standards such as the Common Public Radio Interface (CPRI) which transport digital, sampled radio signals between digital base stations and radio antenna units, the fronthaul of the mobile network. The current deployment of 5th generation mobile networks (5G), has made clear that the use of sampled radio signals is no longer possible due to the higher bandwidths and the use of multi-antenna techniques. Analog radio-over-fiber becomes more attractive, as do forms of analog-like transport (multi-level and multi-tone signals) in order to make efficient use of bandwidth and enable the use of lower-cost components in a new fronthaul. This talk will explain how radio-over-fiber is among a range of different alternatives for the new fronthaul, and how modulation schemes which have up to now been the preserve of analogue radio over fiber, may offer solutions to digital transport.

James Webb Space Telescope: A Bird’s Eye View

ABSTRACT:
This James Webb Space Telescope (JWST), a partnership of the National Aeronautics and Space Administration (NASA), European Space Agency (ESA), and the Canadian Space Agency (CSA), was successfully launched on December 25, 2021, and is now at its parking orbit 1.5 million km from Earth. Operating in the infrared, its scientific goal is to show us the formation of the first stars and galaxies, tell us about exoplanets, the formation of elements that make up life, and much more. Its 6.4 m mirror made of 18 hexagonal pieces, makes it a hundred time more powerful than the legendary Hubble Space Telescope. The cutting-edge technology of its four science instruments include new generation infrared detectors, a micro shutter array that enables simultaneous observations of multiple galaxies, and a coronagraph for exoplanet detection. This talk will give a brief overview of the science and technology of JWST, and a glimpse of the commissioning and early science images.
