Welcome to the
2008 Global Congress on Communications, Propagation, and Electronics (GC-CPE 2008). This event is intended to represent a major forum for researchers, professionals and students from all over the world to meet in the beautiful and culturally rich city of Amman in Jordan to present their latest research results and to exchange new ideas and practical experiences.
Scope
GC-CPE 2008 main scope includes, but is not limited to the following areas: Photonics and Optoelectronics; Optical Fiber Communications; Microwaves, Antennas and Propagation; Communication Circuits and Sub-Systems; Data and Computer Communications;
GC-CPE 2008 is planned to feature special sessions, keynote talks and tutorial sessions by leading experts, paper presentations, poster shows, demo shows, discussion panels, as well as other interesting technical activities.
Jordan
Coming to Jordan represents a unique opportunity to witness the embrace of history and future. As small in area as it is, Jordan has a rich history spanning thousands of years, a history that a tourist can only admire. Places like Petra and the Dead Sea are only examples of the many one-of-a-kind places to visit in Jordan. On top of all that, Jordan, as a peaceful country in a turbulent area, enjoys extreme levels of safety and security. Jordanian people are internationally known for generosity, hospitality and cultural awareness and tolerance.
Amman
Amman, the beautiful capital of Jordan, is a living model of a large and modern city that has all kinds of tourist attractions.

Wave Propagation in Periodic Structures: Network Theory versus Perturbation Theory and Numerical Methods
Summary
Wave propagation in periodic structures, a central problem in engineering and physics, is discussed from two different perspectives in conjunction with transmission lines and waveguides used as wave filters in the microwave range of the spectrum. The first approach is the transmission matrix formalism of network theory leading to an algebraic eigenvalue problem. The second approach is a field theory approach leading to a Hill type differential equation that is solved either by means of Floquet theory or perturbation theory in what is generally known as coupled mode theory. Emphasis here will be on comparing the perturbation method of multiple scales with the algebraic network theory approach. The comparison is carried out for a periodically loaded transmission line in which the loading is modeled as a dielectric constant with a square wave perturbation or a square wave boundary corrugation. The multiple stopbands of this structure show promise in interference suppression of unwanted signals in ultra wideband systems. The coupled modes approach has a number of attractive design features including bandwidth control and frequency response shaping in a manner paralleling that of antenna array radiation pattern design. The coupled mode equations lend themselves either to an exact solution or a numerical solution. Surprisingly enough, in the cases where an exact solution can be found, it is not possible to evaluate the reflection coefficient accurately due to stiffness of the problem. A numerical method that overcomes this difficulty for linear two-point boundary-value problems is presented.
