01 • The Bottleneck & Our Solution

Stop Stalling at CAD Setup.

Evaluating cutting-edge literature or analyzing competitor patent claims usually stalls at the CAD setup phase. Replicating complex geometries from flat raster diagrams, deciphering vague dimensional data, and establishing de-embedded waveports consumes days of precious high-tier engineering hours.

Nikola RF programmatically extracts dimensional equations and coordinate matrices directly from your provided disclosures, delivering fully parameterized, variable-driven .aedt, .cst, or .wrk workspaces ready to solve with accelerated turnaround.

Traditional Workflow: Manual Drafting

High Latency & Coordinate Drift

  • ×Raster Eye-Balling: Engineers manually guess non-annotated radii, fillet tapers, and inset slot widths from blurry publication PDFs.
  • ×Static Hardcoded CAD: Dimensions are hardcoded without variables, making it impossible to perform parameter sweeps or genetic optimization.
  • ×Exotic Lab Materials: Literature uses obscure or custom laboratory dielectrics with missing loss tangents (tan δ), causing physical fabrication disconnects.
  • ×Port & Mesh Failures: Improper port line calibration, unaligned integration lines, and radiation boundary reflections lead to divergent solutions.

Production-Ready Simulation Workspaces.

You receive native, solver-ready project files engineered according to rigorous industrial standards. Open the project, click solve, and begin immediate parametric studies.

1. Fully Parametric Geometry

Variable-driven dimensions (W_1, L_2, d_feed, p_via) bound directly into the solver parameter tree. Perform instant Nelder-Mead, Quasi-Newton, and Genetic Algorithm optimization sweeps without manual redrafting.

• Optimizer-ready variable hierarchy

2. Industry-Standard Materials

Substrate stackup translation to standard commercial laminates (Rogers RT/duroid® 5880/6002, Panasonic Megtron 6, Isola FR408HR). We apply Kirschning-Jansen dispersion, frequency-dependent ε_r(f), and Hammerstad surface roughness.

• Physical manufacturability guaranteed

3. Ready-to-Solve Boundaries

Calibrated waveport de-embedding, radiation absorbing boundaries (PML / ABC), PEC/PMC symmetry planes, and localized adaptive mesh refinement pre-configured. Eliminates mesh aspect-ratio errors and boundary reflections out of the box.

• Pre-converged Δ|S| < 0.005
03 • Automation Engine

Built on PyAEDT & Headless Simulation.

Our pipeline does not rely on error-prone manual CAD clicks. By utilizing Ansys PyAEDT, COM API bindings, and headless solver automation, we map extracted coordinate matrices directly to native geometry kernels.
