Near-Field Coupling of Polypropylene Dielectric Waveguide Routed Near PCB Board at Terahertz Frequencies
arXiv:2603.24966v2 Announce Type: replace Abstract: The growing demand for high-capacity, low-loss short-reach links in highly integrated electronic systems makes it necessary to understand how terahertz (THz) dielectric waveguides behave in realistic PCB-level packaging environments. In this article, we investigate the channel transmission of a 3D-printed polypropylene dielectric waveguide placed near representative PCB substrates. Continuous-wave THz measurements are carried out for bare,...
OmniSch: A Multimodal PCB Schematic Benchmark For Structured Diagram Visual Reasoning
arXiv:2604.00270v4 Announce Type: replace Abstract: Recent large multimodal models (LMMs) have made rapid progress in visual grounding, document understanding, and diagram reasoning tasks. However, their ability to convert Printed Circuit Board (PCB) schematic diagrams into machine-readable spatially weighted netlist graphs, jointly capturing component attributes, connectivity, and geometry, remains largely underexplored, despite such graph representations are the backbone of practical...
pcbGPT: Automatic PCB Schematic Synthesis from Natural Language Requirements
arXiv:2606.01188v1 Announce Type: new Abstract: Translating natural-language hardware requirements into correct printed circuit board (PCB) schematics remains difficult in embedded, IoT, and wearable development. Designers must choose compatible components, interpret datasheets, add support circuitry, and expose correct interfaces before layout and prototyping can begin, while many such circuits cannot be validated through straightforward simulation.
Structure-Guided Mixed Masked Pretraining and Spatial Continuity Regularization for Printed Circuit Board Defect Detection
Announce Type: new Abstract: Printed circuit board (PCB) defect detection is an essential part of automated optical inspection (AOI); yet it remains challenging in practice because many defects are tiny, low-contrast, and embedded in dense circuit backgrounds. To address these issues, this paper presents a two-phase PCB defect detection framework that combines structure-guided mixed masked pretraining with spatial continuity regularization. In the pretraining stage, we design a sparse...
The intracies of modern camera lens repair (2024)
Sigma 45mm f/2.8 Lens Repair & Analysis [05.12.24] I have a camera gear collection problem and as part of my personal 12 step plan, I restrict myself from purchasing functioning lenses. This sounds illogical, and it frankly is, but it's very hard for me to resist heavily discounted lenses.
Hidden beneath AI chips, Chinese-made circuit boards raise national security concerns in U.S.
Printed circuit boards sit underneath almost every chip, a necessity in nearly every electronic. They make up a quiet but crucial piece of the booming artificial intelligence market, and represent a growing problem for the U.S., because nearly all AI circuit boards, for Nvidia and others, are made in China. Circuit boards present all sorts of opportunities for adversaries to sneak through malicious components.
Inflation inside the electronics you buy may soon become a bit more sticky
Anyone with evergreens in their yard probably knows the familiar feeling of putting their hand on the trunk and coming away with a sticky film on their fingers. This sticky stuff is better known as resin. Under the right conditions, tree resin hardens.
Plane-Wave Excitation of Multi-Beam Modulated Metasurface Antennas
arXiv:2606.02222v1 Announce Type: new Abstract: This paper explores the design of multibeam metasurface (MTS) antennas excited by multi-directional plane-wave launchers. First, we solve the fundamental yet open problem of a plane surface wave (SW) that propagates obliquely to the modulation direction of a sinusoidally modulated MTS. Closed-form expressions are provided to accurately predict the beam pointing angles for any propagation direction of the illuminating plane SW and for any...
OpenGlass: Open-Source Smart Glasses for On-Device Event-Based Gesture Recognition
Announce Type: new Abstract: Smart eyewear enables unobtrusive, context-aware interaction through multimodal sensors and on-device intelligence, but is severely limited by power, memory, and compute constraints in a compact form factor. Open-hardware platforms supporting event-based vision and embedded ML at this scale are rare. This work introduces an open-source smart glasses platform for rapid prototyping of novel sensors and algorithms.
