Keynote Title: Frequency Selective Surfaces for Signal Suppression and Performance Enhancement in Microwave Absorbers
The growing popularity of smart phones and other mobile gadgets causes the cellular networks coverage to be provided almost everywhere. However, in certain areas, these cellular signals might not be able to tolerate with the security system, such as in airports and hospitals. Due to this, there is a need of cellular signal suppression to provide area isolation. There are various techniques that can be used to attenuate the cellular signals including the employment of the mobile phone jammer . Nonetheless, this technique is not environmental friendly and less efficient resource. Therefore, the deployment of frequency selective surfaces (FSS) is one of the potential alternatives. In the indoor environment, FSS patch type can be realized by transforming the wall into a frequency-selective wall, thus, modifying the electromagnetic architecture of the buildings. Therefore an electromagnetic quiet room that has the ability to permit and block certain frequency range can be realised. The FSS can also be integrated in the design of microwave absorber. By careful design, a low profile microwave absorber which is important in most of mobile systems can be designed with improved absorption efficiency and operating bandwidth.
Assoc Prof Dr Fauziahanim Che Seman received the B Eng degree in Electrical- Communication from Universiti Teknologi Malaysia. In 2002, she was awarded M Eng degree in Communication Engineering from Kolej Universiti Tun Hussein Onn, now known as Universiti Tun Hussein Onn (UTHM). She received her PhD in electrical engineering Queens University Belfast, Northern Ireland in 2011. She serves as academician in Department of Communication Engineering, Faculty of Electrical Electronic Engineering at Universiti Tun Hussein Onn Malaysia (UTHM) since 2002. She is also a research fellow in Research Center for Applied Electromagnet (EMCenter). She has authored and co-authored over 40 referred journal and conference technical papers on topics related in frequency selective surfaces, antenna design and applied electromagnetic. Due to her significant contributions she has been awarded as Top Scopus Index Author by Publisher’s Office, UTHM in 2014. Since 2011, she actively served as an associate reviewer for more than 20 international conference. Since 2014, she serves on the IEEE Malaysia AP/MTT/EMC Joint Chapter as executive committee. She is actively involves with industrial – academia activities and currently has joint research collaboration with Silterra and Telekom Malaysia RnD.

Keynote Title: TM Legacy Copper Cable Readiness for the Expansion of the High Speed Broadband in Malaysia
Since the commencement of High Speed Broadband (HSBB) in March 2010, it has rapidly expanded throughout Malaysia and demonstrates a positive growth in the number of subscription. One of the key technologies which deliver HSBB to the customer premises in this country is the Digital Subscriber Lines (xDSL) technologies which utilize Telekom Malaysia’s (TM) legacy twisted pair copper cables as the medium of transmission. Even though the optical access network inherently has higher transmission capacity, upgrading the access network entirely to fiber remains costly and requires a lot of effort on man power and infrastructure which comes to the use of the existing copper cable. Hence, a research in TM’s twisted pair copper cable and its readiness for the HSBB implementation is of the uppermost priority. One the challenges of HSBB deployment is the existing of impairments in copper lines such as bridge tap especially at customer’s premises or cable imbalance. The speed performance was found significantly drop or become unstable lines due to these impairments. Thus, characteristic and behaviour of the impairments in copper cable have been studied in order to ensure the readiness of HSBB penetration in Malaysia. The successful of HSBB phase 1 consequently inspired TM to carry out the implementation of the High Speed Broadband Initiative 2 (HSBB2) and Sub-Urban Broadband Initiative (SUBB) throughout the country.
