While suppressing the losses of the guiding wave tube, branch the wave and measure the reflected power ratio, etc., in the sub-guiding wave tube.
The porous directional coupler is a coupler with numerous coupling holes created in two waveguides (WRJ-10) that share the E-plane, demonstrating good directionality over a wide bandwidth. We analyzed the electromagnetic waves within the waveguide when 10 GHz microwaves (TE10) were incident at the ports of the waveguide. The diameter of the holes is larger closer to the center, and the center positions of the holes are arranged at intervals of one-quarter of the wavelength within the tube.

basic information
【Features】 ○ The forward wave entering from Port 1 passes through the opening connecting the main waveguide and the auxiliary waveguide, → and is transmitted to Ports 2 and 4 in a constant ratio. ○ The wave output from Port 4 provides an output proportional to the forward wave of the main waveguide, → while the wave output from Port 3 provides an output proportional to the backward wave of the main waveguide. ○ The opening is designed so that the wave transmitted through the main waveguide is almost lossless, → resulting in the wave traveling through the auxiliary waveguide being very small compared to the wave traveling through the main waveguide. ○ Analysis material properties (air): → Relative permittivity (real part) 1, Relative permittivity (imaginary part) 1, Relative permeability (real part) 1, Relative permeability (imaginary part) 1 ○ Analysis conditions: Frequency 10GHz ○ Input conditions: TE10 wave input at Port 1 ○ Boundary conditions: Set non-reflective boundary conditions at each port ● For more details, please contact us or download the catalog.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon's software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
