Higher Institutions’ Centre of Excellence (HICoE) is an important initiative of the Ministry of Higher Education in its effort to inculcate research culture in Malaysian Institutes of Higher Learning. Centres of Excellence represent vehicles for researchers and post graduate students to undertake multidisciplinary research, that are internationally recognised, meeting global standards and in areas of national importance.
Accounting Research Institute (ARI) was accorded the HICoE status since 2010 under the research and innovation thrust driving its research niche in Islamic Financial Criminology.
Accounting Research Institute (ARI)
The Accounting Research Institute (ARI) is proud to be recognized as ISLAMIC FINANCIAL CRIMINOLOGY RESEARCH BODY OF THE YEAR at ACQ Award 2015. This recognition greatly reflects ACQ’s strong effort to promote and advocate leading academic research in Islamic Finance globally. This award reinforces ARI’s reputation as a prominent research centre and we appreciate the recognition it provides us - that ARI aspires to continuously support the prosperity of Islamic Finance and aims to become a reference centre for global research in Islamic Finance Governance and Financial Criminology

Researchers at Universiti Teknologi MARA in Malaysia have succeeded in using ionised gas in a common fluorescent light tube as an antenna for a Wi-Fi Internet router.
Wi-Fi routers are essentially two-way radios that connect digital devices to the Internet. But in many buildings, providing complete coverage is a challenge. Radio “dead spots” can occur in areas where solid walls or appliances block a router’s signal entirely, or degrade it to become so weak that a portable Wi-Fi device, such as a tablet or phone, cannot connect reliably.
When electricity flows through the argon-mercury vapour in a fluorescent tube, it forms an ionised gas or plasma. Plasma has conducting properties comparable to a common metal radio antenna. This allows an attached router to send and receive radio signals through the light tube on the standard 2.4-gigahertz Wi-Fi frequency in exactly the same way it does through a regular antenna. The router’s radio waves can ionise the gas in the tube, so it acts as an antenna whether the light is on or off.
According to the research team, the plasma found in a standard 62-centimetre light tube is highly conductive and signal measurements on a test device show that it’s strong and stable. Thus plasma compares favourably with standard metal Wi-Fi antennas for transmitting and receiving.
The prototype antenna consists of a fluorescent tube that connects to the router through a tuned wire coil in a sleeve slipped over one end. The coil passes the router’s radio signal through the glass of the fluorescent tube and into the plasma.
The team says that multiple antennas could be connected to a single router through a building’s electrical wiring using existing Wi-Fi standards. This would create a separate antenna in every room where there is a dedicated fluorescent light fixture and provide low cost building-wide wireless Internet coverage.
Further studies by the team may include adding more fluorescent tubes in various configurations to investigate the capability and performance of multiple plasma antenna arrays. One possible application could involve installing this technology in outdoor billboard lights. Each plasma antenna array would then be integrated with a Wi-Fi router to provide large-scale, system-wide wireless communication.
