دلالة النص على مبادئ الشريعة الإسلامية في الدساتير العربية وأثره في تنظيم مبدأ المساواة بين المواطنين

This research is about the effect of text meaning on the constitutional rule that related to the Islamic Sharia principles. The Islamic Sharia principles are the source of legislation in the Arab constitutions. It will also look in the impact of this constitutional rule on organizing the principle of equality among citizens in various fields; equality in front of the law and judicature, and equality in rights and freedoms. In particular, this research highlights how the impact of text on the constitutional rule affects on organizing the equality between Muslim and non-Muslim citizens, also between men and women of Muslim citizens. Thus, this research has been split into four topics that addressed respectively as follows: First, what is Islamic Sharia and Legislation in Islamic Fiqh (doctrine). Second, the semantics of multiple formulations of the Islamic Sharia principle as a source of legislation in the constitution. Third, the principle of equality in both, the Islamic Sharia and the positive law. Finally, the impact of the text on the Islamic Sharia principle of Arab constitutions in organizing the equality principle among citizens. The research concluded with set of results that can be summarized as follows: Every formula that has been used in the constitutional rule of the Islamic Sharia principle in the Arabic countries has a different semantics and results that lead to different obligations in the way of organizing the equality principle in the legislative bodies either in constitution's document or in ordinary laws. Also, the research concluded that the Islamic Sharia as a public principle doesn't conflict with the positive law in recognizing the equality principle among citizens in different fields, but the conflict is in the understanding and application of some fields of equality among citizens in different religions and genders. The researcher came with set of recommendations including clarifying wording of the text that related to the Islamic Sharia principle in the Arab constitution rules. These clarifications should prevent any other interpretations. In addition, the researcher suggested to adopt this formula: the original principles of Islamic Sharia is the main source of legislation. Also, formulations of equality principle among citizens in all its manifestations in the constitutions must be consistent with the original Islamic Sharia principle. Also, all the texts that related to the equality among citizens, and between men and women should included the sentence "with no conflict with the original Islamic Sharia principles".

Tunable Metamaterials

Metamaterials (MTM) are composite materials that provide some unique characteristics which are not available by nature. But there is one major drawback or limitation of MTM which is its fixed and narrow working frequency region. To overcome this limitation, there are few techniques, presented in this thesis, to vary the working frequency band of MTM. As MTM are artificial materials, so there are various resonators available in literature, presented for MTM. In this thesis, three resonators, split ring resonator (SRR), S-shaped resonator (SSR) and single side paired S-ring resonator (SSPSRR) have been chosen from literature and different techniques to shift their resonant frequencies are presented. For SRR, a tunable case i.e., inner ring shorted split ring resonator (IRS-SRR) is pre- sented in this thesis. The analytical expression of the effective permeability of IRS-SRR is calculated and for the verification of the analytical work, the experimental results are also included in this thesis. The analytical expression for the effective permeability of SSR is also presented in this thesis. Two tunable or modified cases of SSR, i.e., bottom metallic strips shorted S-shaped resonator (BSSR) and top-bottom metallic strips shorted S-shaped resonator (TBSSR) are presented in this thesis. The analytical expressions of the effective permeabilities of BSSR and TBSSR are also calculated. For verification of the analytical work of SSR, BSSR and TBSSR, experimental results are included in this thesis. Similar to SSR, the analytical expression of the effective permeability of SSPSRR is presented in this thesis and the experimental results are also included to verify the analytical work. Two tunable cases of SSPSRR, i.e., bottom metallic strips shorted single side paired S- ring resonator (B-SSPSRR) and top-bottom metallic strips shorted single side paired S-ring resonator (TB-SSPSRR), are also presented in this thesis along with experimental results. Other than the tunable cases of various resonators, rotation of resonators is presented in this thesis as a technique to vary the working frequency of MTM. This technique has been applied on SSR, SSPSRR and their respective tunable cases in this thesis and the vexperimental results are presented for justification of this technique. There are number of devices (made using MTM), are available in literature. All these devices can be upgraded to work as tunable devices using the techniques presented in this thesis.
