The first is the development of a numerical technique to compute the field patterns within a longitudinally invariant rectangular waveguide filled with a chiral material. The finite-difference method is used because of the complex nature of the solution to the chiral rectangular waveguide. Based on ...
In the case of rectangular waveguides, visualize the difference in terms of a physical connection. If theupside of a port is aligned with theupside of the waveguide carrying the excitation signal, the signal at the port is in phase with what is expected. But if theupside of the port is c...
rectangular waveguidesecondary emissionRecent communication satellites are designed to cater to a constantly increasing number of users, thus demanding increasingly higher bit rates. This combination implies increasing power levels of RF equipment downstream from the power amplifiers to the OMUXs. In this ...
The near field leaky-wave focusing antenna using the inhomogeneous rectangular waveguide is proposed and a design method is presented. The height of the waveguide broad wall is inhomogeneous to obtain focusing effect at a desired position. Simulation results and measured results at Ka-band are presen...
than 0.7 THz, while it is greatly decreased when the frequency is lower than 0.7 THz since it is not supported by the rectangular waveguide again. The far-field radial pattern and angular distribution of the rectangular wave- guide at 1 THz is shown in Fig. 2(e). In order ...
indicating that the whole ribbon is a single crystal. The SAED pattern could be indexed with its single crystal lattice constants, and it confirms that the crystal grows along the [010] direction, i.e., the π–π stacking direction of CHICZ molecules. Such direction of this molecular packin...
Moment Method technique is applied to a rectangular waveguide in an infinite ground plane and crossed-dipole, when the latter used as a near-field probe of the former. Crossed-dipole is used to measure both co-pole and cross-pole near-field components simultaneously. The scattering properties of...

1 is a cylindrical waveguide junction having three rectangular waveguide output ports 20a, 20b and 20c. However, for purposes of this invention the mode coupler 18 may be adapted with any number of a plurality of rectangular waveguide output ports. The incident plane wave field is focused to ...
The rigorous CAD of a class of rectangular and circular waveguide cavity filters which are coupled by rectangular and/or circular irises is described. The design theory is based on the full-wave mode-matching method for three key building block elements (asymmetric rectangular double-step, asymmetri...
