Searching for Better Plasmonic Materials

In this post i want to discuss about what’s best material for plasmonic device application except  considering graphene. I want to find a materials with low loss, high confinement and easy fabrication.

Review on smith chart and it’s applications

In this post we want to discuss about smith chart, in microwave transmission line we use it, for matching problems.

Importance of impedance matching and coupling mechanism(1)

And older story in microwave and THz  or higher frequency range is finding a way that we have high effieceincy coupling. So i will discuss about mechanism coupling and phase and impedance matching.

Selectivity and sensitivity in SDR Hardwares

Finally we worked on RTL-SDR and HackRF One and USRP in practical test and different moudlation like GFSK,DVB-T,ATSC,OFDM,DMR.With all of them we can see spectrum, it is not final purpose, we emphasize ,purpose is data in digital radio communication.So which SDR hardware can handle  data extracting with different moudation and protocols like GSM or even LTE and so on.
