Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering

Advanced Optical Materials, EarlyView.
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

A Survey on Elliptic Curve Cryptography

INTERNATIONAL JOURNAL OF RESEARCH IN ADVANCE ENGINEERING, 2015
Elliptic curve cryptography (ECC) is the most efficient public key encryption scheme based onelliptic curve concepts that can be used to create faster, smaller, and efficient cryptographic keys. ECCgenerates keys through the properties of the elliptic curve equation instead of the conventional method ofkey generation.
