Waveguide Examples Using XFdtd®

Remcom’s XFdtd software is well-suited for microwave device design and analysis, including complex waveguide systems. Our Waveguide Examples booklet features five waveguide applications, each with downloadable project files to help engineers get started quickly and explore practical design workflows.

Examples include: 

•    Microstrip Gap Waveguide on Electronic Band Gap Substrate
•    Rectangular Waveguide Mode Converters
•    Waveguide Cross-Coupled Filter Simulation
•    Slotted Waveguide Antenna
•    Wideband Pseudo-Elliptic Waveguide Filter

As waveguide systems increase in complexity, XFdtd streamlines the process with powerful waveguide excitation capabilities that support efficient design, analysis, and optimization. Whether working with slotted waveguide antennas featuring intricate geometries or advanced filters requiring precise coupling, XFdtd enables accurate simulation of real-world performance.

Waveguide ports provide reliable modal excitation, while S-parameter results deliver clear insight into signal behavior across designs. Engineers can also explore mode converters and emerging technologies, such as microstrip gap waveguides on EBG substrates, within a single simulation environment.

With advanced meshing and fast computation, even highly detailed structures can be analyzed efficiently. From concept through validation, XFdtd supports the development of reliable, high-performance waveguide designs.
