Research Output | Dar Al-hikmah Library | IIUM Only

This study reports the performance of an Archimedean spiral antenna, which exhibits unidirectional circularly polarized radiation patterns with a peak gain >8 dBic in the lower (2.4–2.485 GHz) and upper (5.15–5.35 and 5.725–5.875 GHz) Wireless local area network frequency bands. The required backlobe suppression and impedance match are ob

A Light Material for Wind Turbine Blades
Research Output | Dar Al-hikmah Library | IIUM Only

Nowadays, people have built mega-watt scales of wind turbines to generate electricity from wind energy. These big scales of wind turbine blade need lighter materials in order to optimize the generation of electricity. Due to this issue, purpose of this paper is to find a light material which is suitable to be used in making wind turbine blades. The

Performance of Archimedean Spiral Antenna Backed by Fss Reflector
Research Output | Dar Al-hikmah Library | IIUM Only

The use of a backing cavity composed of a frequency selective surface (FSS) above a metal plate as a means to suppress the back lobe radiation and increase the gain of an Archimedean spiral antenna that operates from 3 to 10 GHz is investigated. The FSS is designed to reflect signals in the upper band (7-10 GHz) with a loss of <;0.25 dB, and al

Strategic Innovation from Inspiration to Impact

The Influence of Israelites Narratives in Business Research from Islamic Perspectives
Research Output | Dar Al-hikmah Library | IIUM Only

The narratives for business research from Islamic perspectives are from the primary sources, Al-Quran and Sunnah (traditions)of Prophet Muhammad (peace be upon him). Most business researchers are not proficient to use the primary references but to rely on narratives that are translated in English and other languages that are conversant with the res

Preparation and Characterization of titania-Cyanopropyltriethoxysilane Sorbent for the Extraction of Polar Aromatic Amines
Research Output | Dar Al-hikmah Library | IIUM Only

A new titanium(IV) butoxide-cyanopropyltriethoxysilane (Ti-CNPrTEOS) hybrid material was successfully synthesized for the use as sorbent for the extraction of polar aromatic amines. The sorbent was synthesized by hydrolysis and condensation of titanium(IV) butoxide and cyanopropyltriethoxysilane with the presence of hydrochloric acid as catalyst vi
