rfx Gallery

A visual tour of structures, fields, outputs, and differentiable calculations. The slab and waveguide pages state their reference comparisons and supported gradient scope. The patch page is explicitly diagnostic because its stored port setup does not pass current preflight; its plots and derivative are not RF validation. Read the status and limits on each page before reusing a number.

Dielectric Slab

Reflection and transmission of a dielectric slab vs the exact Fresnel curves

A plane wave at normal incidence on a lossless dielectric slab. Reflection and transmission track the exact transfer-matrix curves to ~1%, and jax.grad returns dT/dd matching the closed-form derivative. See it →

Patch Antenna Diagnostics

Patch-antenna S11 diagnostic from a setup that fails preflight

File-format, plotting, and AD/FD artifacts from a port setup that does not pass current preflight. The plotted RF values are not validation evidence. Read the limits →

Rectangular Waveguide

TE10 mode propagating down a WR-90 rectangular waveguide

The TE10 dominant mode down a WR-90 X-band guide. |S11|/|S21| match the exact matched empty-guide answer at the CPML floor, and jax.grad differentiates the transmission through a dielectric fill. See it →
