Analysis of Nonlinear Cylindrical Waveguide Taper Using Modal Matching Technique
Nonlinear tapered waveguide sections are often needed in the microwave/millimeter-wave system to connect the two waveguides of different radii. The presence of such a taper inevitably introduces unwanted parasitic modes and reflections. The modal matching technique is a powerful computer friendly method for analyzing horn antennas or nonlinear waveguides in which the actual profile is replaced ...
متن کاملIty of Modes in a Parallel Plate, Anisotropic Waveguide Using a Modified, Coordinate Transformation
The excitation of forward and backward, Electromagnetic (EM) modes and fields in an anisotropic, parallel plate waveguide (meeting Dirichlet and Neumann boundary conditions), is studied, using a modified coordinate transformation which reduces Maxwell’s equations to the form of a Helmholtz wave equation satisfying Dirichlet and mixed-partial derivative boundary conditions. The EM modes and fiel...
متن کاملPlastic Optical Fiber Coupler with High Index Contrast Waveguide Taper
A simple low-cost Y-branch plastic optical fiber (POF) coupler which can be assembled easily by the end users has been developed. The acrylic-based Y-Branch POF coupler consists of input POF fiber, a middle high index contrast waveguide taper and output POF fibers. The optical device is based on a 1 × 2 Y-branch coupler design with a middle high index contrast waveguide taper. Nonsequential ray...
متن کاملGeneralized Lorentz Coordinate Transformation
This paper derives equations for generalized Lorentz coordinate transformation based on a simple principle that only the wave equation must be form invariant and valid in both coordinate systems. The usual requirement that the speed of light is a universal constant and thus has an identical value in any inertial coordinate systems is removed. This leads to some interesting conclusions and possi...
متن کاملCoordinate Transformation in Nanorobotics
As it is the well known, the nanorobotics is the multidisciplinary field that deals with the controlled manipulation of atomic and molecular-sized objects and therefore sometimes is called molecular robotics. In order to design control algorithm for control of a nanorobot motion in a multipotential field, one should start with the related coordinate transformations. It has been done in this pap...
