E-Plane Tee: (Series Tee) An E-Plane Tee is a waveguide lies in which the axis of its side arm is parallel to the E Field of the main guide as shown in figure. When the waves are fed into the side arm(port3) the waves appearing at port1 and port2 of the collinear arm will be in opposite phase and to

Introduction: Now we are in the twenty first century‚ the era of ‘Information technology’. There is no doubt that information technology has had an exponential growth through the modern telecommunication systems. Particularly‚ optical fiber communication plays a vital role in the development of high quality and high-speed telecommunication systems. Today‚ optical fibers are not only used in telecommunication links but also used in the Internet and Local area networks (LAN) to achieve high signaling

For this combination to propagate as a single entity with a common propagating velocity‚ the horn or waveguide must have anisotropic surface-reactance properties: properties that are satisfied by the corrugated surfacc. It is worth pointing out that hybrid modes can also be supported by other means‚ such as waveguides or horns partially filled with dielectric

Waveguides – A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH – Fiber-to-the-home 4. Simplex – a. A link that can only carry a signal in one direction. b. A fiber-optic cable or cord carrying a single fiber. Simplex cordage is mainly

transmitters emit many different modes. Lower order modes travel a shorter distance. Some of these light rays will travel parallel to the center of the fiber while repeatedly bounce off the cladding/core boundary to high order modes their way the waveguide. The modes that enter at sharp angles are called high-order mode‚ which having direction towards cladding. These modes take longer path to travel through the fiber than the low-order modes and therefore it cusses of modal dispersion. One

the first years of microwave development the Rectangular Waveguide become the dominant waveguide structure largely because high-quality components could be designed using it. One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined other waveguide types. Ridge Waveguide offered a step in that direction‚ having one or more longitudinal
