X Band GaN Based MMIC power amplifier with 36.5dBm P1-dB for space applications
An X-Band Monolithic Microwave Integrated Circuit (MMIC) High Power Amplifier (HPA) with coplanar waveguide (CPW) based on AIGaN/GaN on SiC technology is presented in this paper. Coplanar waveguide technology (CPW) is ...
Negative refraction and subwavelength focusing using photonic crystals
We review certain novel optical properties of two-dimensional dielectric photonic crystals (PCs) which exhibit negative refraction behavior. We investigate two mechanisms which utilize the band structure of the PC and lead ...
Spectral negative refraction and focusing analysis of a two-dimensional left-handed photonic crystal lens
(American Physical Society, 2004-11)
We report the spectral refraction analysis and focusing properties of a two-dimensional, dielectric photonic crystal (PC) slab in freespace. A transverse electric polarized upper band of the crystal is used. The measured ...
Experimental analysis of true left-handed behaviour and transmission properties of composite metamaterials
We report the true left-handed transmission of a composite metamaterial (CMM) consisting of periodically stacked split-ring resonator (SRR) and wire elements. The negative permeability (μ < 0) gap is demonstrated explicitly ...
