A novel reconfigurable radial composite right/left-handed transmission line (CRLH-TL) is proposed and used in a dual-band antenna with frequency agility. Varactors are used to tune the TL dispersion ...

Although enthusiasm for transradial access for neurointerventional procedures has grown, a unique set of considerations bear emphasis to preserve safety and minimize complications. In the first part ...

Sea anemones may look alien, but scientists just found out they're hiding an ancient body 'blueprint' – one that most animals ...

Researchers Trace Evolutionary Trajectory of Starfish's Unique Symmetry Through a 500 Million-Year-Old Fossil The star shape of the starfish (five arms) is intriguing to many marine aficionados. But ...

The fundamental symmetries of parity and time are now being exploited to enable the spatial guiding and selection of propagating radiation, and could ultimately underpin a new generation of ...

In today's system-on-chip designs, both digital and analog parts of a circuit will be implemented on the same chip. Parasitic mismatch induced by layout will affect circuit performance significantly ...

Electrolytes and electrodes in protonic ceramic electrolysis/fuel cells (PCECs/PCFCs) can exhibit significant chemical strains upon incorporating H2O into the lattice. To increase PCEC/PCFC durability ...

A novel type of nonlinear symmetry breaking in symmetric plasmonic oligomers is reported. By monitoring the strength of the second-harmonic signal while changing the polarization angle of the pump, we ...
