I need a full electromagnetic design for a dielectric lens – or a compact horn‑lens combination – that concentrates microwave energy at 2.45 GHz from an existing 1 kW source in a controlled lab/industrial setting. The goal is to maximise the energy delivered to a small focal spot (target ≈ 2–3 cm at a defined distance), so the work must revolve around: Directivity Gain High power‑density focusing at the target spot Please model, optimise and document the antenna‑lens using a recognised 3‑D EM solver such as CST Studio Suite, HFSS, FEKO or similar. I will rely on your simulations to validate return loss, beam pattern, peak gain and the size of the focal region before we commit to fabrication. Deliverables Native simulation project files and exported 3‑D geometry (STEP/STL/IGES) Complete material call‑outs for the dielectric (εr, loss tangent, machinability notes) Radiation pattern plots, gain vs. frequency, S‑parameters and near‑field focus maps Brief design report summarising methodology, optimisation steps and expected performance Manufacturing drawings or print‑ready files so the lens can be machined or 3‑D printed without further work Acceptance criteria will be the achievement of the specified performance in simulation, verified through the documents above and a quick online design walk‑through with me. If you have experience delivering high‑gain, highly directive microwave lenses or horn‑lens hybrids for power‑beaming or high‑intensity focusing at 2.45 GHz, let’s get started.

Hi, Your project to design a high-directivity microwave focusing system at 2.45 GHz using a dielectric lens or horn-lens hybrid is very interesting, especially given the goal of concentrating energy from a 1 kW microwave source into a small focal region (~2–3 cm). I would be glad to assist with the full electromagnetic design, optimisation, and simulation validation required before fabrication. My experience includes electromagnetic and multiphysics simulation, high-frequency structures, and energy-focused systems, using tools such as ANSYS HFSS / CST-type workflows to evaluate radiation characteristics, impedance matching, and near-field focusing performance. For this project, I can support the following steps: • Antenna–Lens Architecture Development – Evaluate dielectric lens vs horn-lens hybrid configurations – Define focal distance, aperture size, and optimal geometry for maximum directivity and power density • Full-Wave Electromagnetic Simulation – Model and optimise the design in a 3-D EM solver – Analyse S-parameters (return loss), radiation patterns, gain vs frequency, and beam focusing behaviour – Generate near-field intensity maps to verify the 2–3 cm focal region • Material & Manufacturing Definition – Recommend dielectric materials (εr, loss tangent) suitable for machining or 3-D printing – Provide machining-ready or print-ready geometry Best regards,

Hello, I have solid experience in RF and microwave system design, including antenna modeling and optimization using full-wave electromagnetic simulation tools such as CST Studio Suite and HFSS. Your requirement to focus 2.45 GHz microwave energy from a 1 kW source into a small focal region aligns well with high-gain antenna and dielectric lens optimization work I’ve done for directive RF systems. For this project, I would design and simulate either a dielectric focusing lens or a compact horn-lens hybrid, optimizing the geometry and dielectric parameters to maximize directivity, gain, and power density at the defined focal distance. The process will include return-loss optimization, beam pattern shaping, and near-field analysis to achieve the target ~2–3 cm focal spot while maintaining good efficiency at 2.45 GHz. Deliverables will include the native EM simulation files, 3D CAD geometry (STEP/STL), detailed radiation and near-field plots, S-parameters, and a concise design report with material recommendations and manufacturing guidance for machining or 3D printing. I can also walk you through the simulation results and design decisions during a short review session. I’d be happy to share examples of previous RF/antenna design work and discuss the focal distance, aperture constraints, and preferred manufacturing method before starting.
