I need a complete CST Studio Suite 2021 workflow that starts with a single 12 × 12 mm unit cell and ends with a fully simulated 16 × 16 reflectarray, all driven by PIN-diode control logic written in MATLAB. Geometry & materials • Stack order: 35 µm copper patch, 1.6 mm FR-4, 35 µm ground, 0.8 mm FR-4 • On the underside place a MACOM MADP-000907-14020 PIN diode plus an RF choke that links back to the patch through vias. Performance target The critical metric is a phase shift of 180° ± 20° across 3 – 5 GHz. Please make sure the simulation reports both S-parameters and far-field patterns so I can confirm this window is met before we scale up. After validating the unit cell, replicate it into a 16 × 16 lattice, export the array model, and verify global performance in CST. MATLAB deliverable Write a concise script that toggles each diode between ON and OFF states, updating the CST excitations (or an exported scattering-matrix) so I can sweep beam-steering cases from MATLAB directly. Deliverables • CST project files for the standalone unit cell and the 16 × 16 array • MATLAB (.m) code controlling the diode states • PDF report summarising geometry, simulation setup, S-parameters, far-field plots, and confirmation of the 180° ± 20° phase requirement Please keep screenshots, CST version info, and any custom macros inside the PDF so everything is reproducible on my side and should be editable.

Hello, I can develop the complete CST Studio Suite 2021 + MATLAB workflow for your PIN-diode controlled 16×16 reflectarray. My scope includes: Design and simulation of the 12×12 mm unit cell with the specified copper/FR-4 multilayer stack. Integration of the MACOM MADP-000907-14020 PIN diode, RF choke and vias. Modeling diode ON/OFF states and simulating the 3–5 GHz range. Extraction of S-parameters, reflection phase and far-field patterns. Verification of the required 180° ±20° phase shift before array scaling. Replication into the 16×16 reflectarray and global CST performance validation. MATLAB .m automation for controlling diode states and sweeping beam-steering configurations. Delivery of editable CST projects, MATLAB scripts and a detailed PDF report containing geometry, setup, screenshots, plots, CST version information and custom macros. I will prioritize unit-cell validation first to ensure the required phase performance is achieved before proceeding with the full array. Regards,
