Are your patio pavers looking dull and dirty? Learn how to clean them safely by hand, with tips from our experts.

We experimentally demonstrate the structural tuning of the waveguiding modes of line defects in photonic crystal (PC) slabs. By tuning the defect widths, we realized efficient single-mode waveguides ...

A new vertical transition using a trough line, a slab line and shielded multilayer coplanar waveguides (SMCPW) was proposed in order to develop a DC to 50 GHz band low loss LTCC hermetic surface ...
