Three-port microstrip T junction

Explore the device model, recorded field evolution and original response exports in Microwave FDTD Studio.

01 · MODEL & PORTS

Model & ports

Device geometryTransparent geometry with three planar conductor-to-ground lumped ports.
02 · RECORDED FIELDS

Recorded fields

Recorded EM-field slices show excitation spreading through the T junction and its three branches. Original 24 frames at 12 fps; playback time is not simulation runtime.

04 · FREQUENCY RESPONSE

Frequency response

Frequency-response overviewMagnitude, return loss, VSWR, input impedance and normalized-impedance Smith-chart views across 1–5 GHz.
05 · TEMPERATURE DISTRIBUTION

Temperature distribution

Spatial temperature results use the recorded electromagnetic load and thermal model. They are separate from port-signal prediction; compare numerical temperature scales rather than colors alone.

Temperature distributionTemperature is mapped over the device geometry using the original °C scale. The image is a spatial temperature result, not a time trace or measured validation.
Result interpretation

Images preserve their original pixels, axes and color scales. Videos preserve source resolution and frame timing. These are recorded exports, not a live solver.

Prediction quality requires checks against longer or withheld recorded data. A smoother curve alone does not establish accuracy or convergence.
