We will introduce a case where the reflection coefficient obtained as a result of analysis was compared with the theoretical value!
When a dielectric such as polyethylene is filled in a rectangular waveguide, electromagnetic wave reflection occurs at the boundary with air. Considering a system where polyethylene is filled in part of a rectangular waveguide of standard WRJ-5, the distribution of electromagnetic waves was analyzed using the finite element method. As a result, it was found that the absolute value of the electric field on the polyethylene side is constant, indicating that there is no reflection at the output surface (the impedance boundary is correctly set). [Case Summary] ■ Analysis Module: PHOTO-WAVEjω ■ Analysis Results - It can be seen that there is no reflection at the output surface since the absolute value of the electric field on the polyethylene side is constant (the impedance boundary is correctly set). - In the calculation of the scattering matrix, the characteristic impedances of air and polyethylene were set as ZAir = 279.052Ω and ZPE = 156.987Ω. *For more details, please refer to the related links or feel free to contact us.

Company information
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.
