E-Band Filters Based on Substrate Integrated Waveguide Octagonal Cavities Loaded by Complementary Split-Ring Resonators

2015 IEEE MTT-S International Microwave Symposium, 2015
In this paper, substrate integrated waveguide (SIW) octagonal cavities in conjunction with octagonal complementary split-ring resonators (CSRRs) are used to propose compact narrow bandpass filters at E-band. Short circuited slots are employed as coplanar waveguide (CPW) to SIW transitions as well as matching elements between adjacent stages of filters.

Buoyancy-driven convection in two superposed fluid layers in an octagonal cavity

International Journal of Thermal Sciences, 2004
Abstract Buoyancy-driven convection in a differentially heated cavity containing superposed layers of air–water, air–silicone oil and silicone oil–water has been experimentally studied. The apparatus is octagonal in plan. It has a nominal diameter of 130.6 mm and a height of 50 mm.

Lasing Actions of Octagonal Quasi-Periodic Photonic Crystal Microcavities

Japanese Journal of Applied Physics, 2006
Lasing actions are obtained from well-fabricated octagonal quasi-periodic photonic crystal (OQPC) microcavities. The defect modes in OQPC microcavities are investigated and compared with the calculation results obtained using the finite-difference time-domain (FDTD) method.

Low loss optical waveguide crossing based on octagonal resonant cavity coupling

Optoelectronics Letters, 2009
A waveguide crossing utilizing a high index contrast material system is presented. The structure is based on coupling with an octagonal resonant cavity inserted at the waveguide junction. It also employs four identical square metal strips placed at the four corners of the waveguide crossing.
