Perkawinan Beda Agama di Republik Yaman Perspektif Hukum Islam dan Hukum Positif

Writing this article wants to describe, related to Yemeni legal regulations, namely the marriage of Muslim women in Yemen. Discussing the annulment of marriages for men who adhere to Islam or Muslims who do not marry Muslim women and women of the book in Yemen. As for the women of the People of the Book who can be married to Muslim men in Yemen, it is necessary to elaborate on the permissibility of marrying women who are not Muslim. Yemen itself fully takes the source of law in the text of the Koran where marriage regulations in Yemen between Muslim men and women of the book are permissible and regulated in Yemen's legal laws. On the other hand, interfaith marriages in other regions related to women of the book cannot be found, in Indonesia, for example, interfaith marriages only describe marriages between Muslims and those who are not Muslim or are not Muslim, there is absolutely no mention of women of the book. For this reason, this article wants to elaborate on the explanation regarding women of the People of the Book, amidst the debate whether or not it is permissible to marry women of the People of the Book, Yemen still adheres to the Al-Quran text which allows Muslim men to marry women of the People of the Book until now.

Scattering of Electromagnetic Waves from a Pemc Circular Cylinder Placed under Wide Double Wedge

A new wedge diffraction function, called as Naveed-Naqvi-Hongo (NNH) wedge diffraction function, is derived and evaluated asymptotically by applying the steepest descent method. It is found that the total field with NNH solution is continuous at the shadow boundaries and gives the well known non-uniform expression for the observa- tion point far from the shadow boundaries. Numerical comparison of NNH solution is made with exact series solution and Pauli-Kouyumjian-Pathak (PKP) result. It is found that the agreement among these three is fairly well. In contrast to the ex- pressions proposed by Kouyoumjian and Pathak, the NNH solution does not need the parameters to switch for the region of validity, hence it is easier to make a numerical code. The validity of NNH wedge diffraction function is further checked by evaluating the diffracted field from a geometry which contains an infinite slit in a perfect electric conducting (PEC) plane. It is further extended to a more complex geometry consisting of two parallel PEC wedges and a perfect electromagnetic conductor (PEMC) circular cylinder which is placed under the PEC wide double wedge. It is found that by using the NNH solution, the results evaluated for some special cases, including the trans- mission coefficient of PEC slit, are in fairly good agreement with the published work. The transmission coefficient and the diffraction pattern of PEC wide double wedge is studied and elaborated by considering a geometry consisting of a coated PEMC cylin- der placed under the two parallel wedges. The cylinder is coated with double positive (DPS) or double negative (DNG) materials. Finally, a comparison of the transmission coefficient of PEC geometry, as evaluated by using NNH solution, is made with the geometry of more practical nature, that is, an impedance slit
