Satellite communication relies on various frequency bands, each with specific characteristics suited for different applications. Here’s a concise overview of the main frequency bands used in satellite systems, their properties, and common uses: Key Considerations:
Waveguide aur semi-rigid cable mein insertion loss ka comparison karna frequency, material, aur design par depend karta hai. Generally: Conclusion: Waveguide mein insertion loss generally semi-rigid cable se kam hota hai, especially high-frequency applications mein. How does the dielectric material affect the losses? Dielectric material ka insertion loss pe effect semi-rigid cable mein kaafi important …
What is Stress? Stress, in the context of physics and engineering, is a measure of the internal resistance of a material to external forces or deformations. It quantifies the force per unit area within a material that arises due to applied loads, pressure, or other external factors. Stress is a fundamental concept in mechanics, particularly …

Artificial Intelligence (AI) aur Machine Learning (ML): 3. Nanotechnology: 4. Sustainable Engineering: 5. Soft Robotics aur Biomechatronics: 6. Electrical Discharge Machining (EDM) ke Recent Advances: 7. Industry 4.0 aur IoT: …
Electrical Discharge Machining (EDM) ek aisi manufacturing process hai jisme electricity ke sparks (chhoti si bijli ke chamak) ka use karke metal ya conductive materials ko shape diya jata hai ya unhe cut kiya jata hai. Isme ek tool (electrode) aur workpiece ke beech mein ek chhota sa gap hota hai, aur is gap mein …
Additive manufacturing ka matlab hota hai “cheezon ko layer-by-layer banakar tayar karna.” Isse hum 3D printing bhi kehte hain. Isme material ko ek ek layer karke add kiya jata hai jab tak poori object ban nahi jaati. Ye traditional manufacturing (jisme material ko kaat kar ya ghis kar shape diya jata hai) se alag hoti …
Seebeck Effect aur Peltier Effect dono thermoelectric phenomena hain, jo electricity aur heat ke relation se connected hain. Inko samajhne ke liye, main inhe simple Hindi-English mix mein explain karta hoon: Seebeck Effect Yeh effect tab hota hai jab do different metals ya materials ke junction (jahan dono milte hain) pe temperature difference hota hai. …
AL6061 ek popular aluminium alloy hai, jo magnesium aur silicon ke mix se banta hai. Ye lightweight, strong, aur corrosion-resistant hota hai, isliye aeroplanes, bikes, aur automotive parts mein use hota hai. T651 ka matlab hai ki yeh alloy age-hardened aur stress-relieved hai. Ab iska age hardening process samajhte hain: Age Hardening in AL6061-T651 Age …
