Linear Array of Center Line Longitudinal Slots Excited by Double Ridge Waveguides [PDF]
Radioengineering, 2018 Slot antennas fed by the wiggly ridge wave¬guides are difficult to construct using a typical milling machine. Therefore, a special type of the double ridge waveguides is introduced here to feed the center line longi¬tudinal slot antennas. Furthermore, in

Analytical Modeling of Resonant Cavities for Plasmonic-Slot-Waveguide Junctions
IEEE Photonics Journal, 2011 Transmittance of a straight junction between two plasmonic slot waveguides can be enhanced by either coupling a perpendicular stub to the input waveguide or inserting an intermediate slot section between the waveguides. We derive analytic expressions for

Comparative Study of Nano-Slot Silicon Waveguides Covered by Dye Doped and Undoped Polymer Cladding
Applied Sciences, 2018 Nonlinear optical dyes doped in optical polymer matrices are widely used for electro-optical devices. Linear optical properties change with dye concentration, which leads to a change in modal properties, especially in nano-structured integrated ...

Slot Array Antenna using Folded Waveguides [PDF]
, 2005 A highly compact slot array antenna using substrate integrated folded waveguides (SIFW) is proposed in this paper. The device has three key components: a non adiating SMA to standard waveguide transition, a power divider from standard waveguide to folded

Advanced Electronic Materials, EarlyView.A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish

Laser &Photonics Reviews, EarlyView.A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic
