I need a Fto based transparent compact patch antenna modelled in CST Studio Suite that can efficiently collect ambient RF power across a very wide band. The end use is pure RF energy harvesting, so instead of targeting a narrow communication band I am after the broadest practical frequency coverage you can squeeze out of a single‐layer or multilayer patch structure without driving size or complexity through the roof. Key requirements • Frequency coverage: “RF frequency wideband” – essentially as wide as we can get while keeping reasonable overall dimensions and good impedance matching. Please propose the exact limits you can reach and back them up with simulation data. • Polarisation: I am open to linear, circular or even dual; pick whichever help...

I need an experienced CAE specialist to help me finish my final-year mechanical engineering project: a fully detailed finite-element model of a small-caliber projectile striking a multilayer bullet-resistant vest. I have already defined the basic geometry and material stack-up in HyperMesh, and the plan is to solve everything with the explicit OpenRadioss solver. What I still require is expert guidance—and hands-on modelling work—so that the simulation reliably predicts: • penetration depth and overall armor performance, • the complete stress and strain fields inside the ceramic and composite layers (stress distribution, strain distribution), • projectile behaviour such as velocity reduction, deformation, and residual velocity, • correct energ...

The complete schematic for my digital-audio signal-processor prototype is ready; now I need it turned into a set of production-ready PCBs in KiCad. There will be three boards in this job. Two will be approximately 110mm by 100mm. The codec board may require a multilayer stack-up. Hopefully the analog IO boards can be accomplished on two-layer boards and accommodate the specified audio connectors along one edge for easy panel mounting. The schematic is already in Kicad 9.0. Footprints and 3d models are in place. You will need to decide the optimal layer order, and route every net with good mixed-signal practices—quiet star ground plane, short high-speed traces, and clean separation of analogue and digital domains. When you are done I should be able to hand the files strai...

...cabinet in a residential setting, that can source at least 5 A, energise an onboard relay, and host a 4 G modem whose Ethernet port breaks out to an RJ-45 jack. Overcurrent-protection circuitry must be designed in from the start so the finished unit survives short-term abuse and meets basic safety marks. The work begins with a schematic that balances efficiency and EMI limits, then moves to a multilayer PCB ready for immediate upload to JLCPCB—Gerbers, drill files, pick-and-place, finished BOM with JLC part numbers, and clear assembly notes. Component placement must reserve adequate clearance for the relay, a uSIM holder, and the RJ-45 while keeping the whole board within a standard 6-module DIN enclosure. Because the modem will sit on the same board, careful attention to...

The board is expressly meant to be a multi-layer RF + digital PCB, so controlled impedance traces, tight length matching, and a clean RF ground strategy are non-negotiable. You will work strictly from my supplied BOM and pin-map, ensuring every net and footprint aligns perfectly with those source documents. While the exact parts list is locked, the design mixes RF front-end blocks with high-speed digital logic—think amplifiers, filters, oscillators, and similar building-blocks—so you should be comfortable routing sensitive analog sections beside fast parallel buses and differential pairs. Deliverables (all generated in KiCad 7 or later): • Complete, ERC-clean schematic • Mult...
I need a fresh multilayer PCB laid out strictly for surface-mount devices so I can move my current concept from breadboard to a fully testable prototype.
