Design of Multiband Fractal Antenna

International Journal of Engineering & Technology, 2018
Fractal is a fragmented geometry which can be segmented into various parts, each part will be the miniature copy of the whole. The main advantages of fractal antennas are its reduced size and multiband operation. These structures have self-similarity properties and fractional dimensions.

Tunable Plasmon‐Enhanced Wide‐Angle Terahertz Perfect Absorption via Lorentz Media

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
A planar graphene‐Lorentz‐DBR structure realizes wide‐angle terahertz perfect absorption through a composite phase‐amplitude matching mechanism. The Lorentz dielectric provides dispersive phase compensation and controlled loss, whereas graphene supports dissipative coupling, enabling high absorption up to 80° incidence and multichannel spectral ...
