"This textbook is intended for a course in electromagnetism for upper undergraduate and graduate students. The main concepts and laws of classical macroscopic electrodynamics and initial information about generalized laws of modern electromagnetics are discussed, explaining some paradoxes of the modern theory. The reader then gets acquainted with electrodynamics methods of field analysis on the basis of wave equation solution. Emission physics are considered using an example of the Huygens-Fresnel-Kirchhoff canonic principle. The representation about strict electrodynamics task statement on the base of Maxwell equations, boundary conditions, emission conditions and the condition on the edge is given. Different classes of approximate boundary conditions are presented, which essentially simplify understanding of process physics. The canonic Fresnel functions are given and their generalization on the case of anisotropic impedance. The free waves in closed waveguides and in strip-slotted and edge-dielectric transmission lines are described.
A large number of Mathcad programs for illustration of field patterns and its properties in different guiding structures are provided. The material is organized for self-study as well as classroom use."

"This book presents the concept of fractional dimensional space applied to the use of electromagnetic fields and waves. It provides demonstrates the advantages in studying the behavior of electromagnetic fields and waves in fractal media. The book presents novel fractional space generalization of the differential electromagnetic equations is provided as well as a new form of vector differential operators is formulated in fractional space. Using these modified vector differential operators, the classical Maxwell's electromagnetic equations are worked out. The Laplace's, Poisson's and Helmholtz's equations in fractional space are derived by using modified vector differential operators.;"

"Transverse electromagetic cell (sel TEM) merupakan perangkat alternatif pengujian EMC (Electromagnetic Compatibility). Namun, frekuensi operasi maksimumnya sangat terbatas sedangkan pengujian EMC mensyaratkan pengujian dilakukan hingga frekuensi 1 GHz. Beberapa pengembangan sel TEM untuk meningkatkan frekuensi operasi malah memperkecil luas keseragaman medan sedangkan peningkatan luas keseragaman medan tidak dapat dilakukan hingga frekuensi tinggi. Coplanar waveguide dapat digunakan sebagai sumber medan yang seragam dan sangat berpotensi untuk digunakan dalam perancangan sel TEM dengan rentang frekuensi yang sangat lebar. Pada tesis ini dilakukan perancangan sel TEM sederhana dengan lempeng coplanar waveguide (CPW) untuk membangkitkan medan elektromagnetik seragam yang dapat beroprasi pada frekuensi 30 MHz - 1.GHz. Hasil simulasi menunjukan sel TEM dapat disusun dari dua buah lempeng CPW identik berukuran 510 mm x 750 mm dengan lebar hot-line s = 440 mm, gap w = 7,69 mm dengan jarak antara lempeng CPW sebesar h = 550 mm. Hasil pengukuran menujukan kesesuaian antara hasil pengukuran dengan simulasi. sel TEM menghasilkan uniform area 30 cm x 50.cm dan memenuhi ketentuan standar IEC 61000-4-20.
A transverse electromagnetic cell (TEM cell) is an alternative device for EMC (Electromagnetic Compatibility) test. The highest operating frequency of TEM cell is limited while EMC test requires testing performed up to 1 GHz. The TEM cell developments to increase the operating frequency has decrease the TEM cell field uniformity area while increasing field uniformity area cannot be done to higher frequency. Meanwhile, coplanar waveguide can be used to generate uniform field and potentially can be used to design a TEM Cells with very wide frequency range. In this thesis, a simple TEM cell was designed with coplanar waveguide plates (CPW) for generating uniform electromagnetic field at frequency 30 MHz - 1.GHz. The simulation results show that the TEM cell can be made by two identical CPW plates which has 510 mm x 750 mm in size, wide of hot-line s = 440 mm, gap w = 7.69 mm and the distance between the CPW plates h = 550 mm. The measurement results show in agreement with the simulastion. The TEM cell produces a uniform area of 30 cm x 50 cm which is in accordance with IEC 61000-4-20 standard."
