While suppressing the loss of the guiding wave tube, branch the wave and measure parameters such as the reflected power ratio 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 inside the waveguide when 10 GHz microwaves (TE10) were incident at the ports of this 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 inside 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 certain 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, → and the wave transmitted through the auxiliary waveguide becomes very small compared to the wave transmitted 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.

At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. 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 reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
