Frozen Mode in Three-Way Periodic Microstrip Coupled Waveguide

چکیده
We demonstrate theoretically and experimentally that a simple periodic fully planar three-way microstrip coupled waveguide exhibits stationary inflection point (SIP). The SIP is third-order exceptional of degeneracy where three eigenmodes the guiding system coalesce to form frozen mode with zero group velocity. Here, shown in reciprocal supporting modes each direction. illustrate occurrence regime by observing dispersion diagram coalescence parameter measure separation coalescing eigenvectors. Results based on full-wave simulations measurements how this not perfect due presence losses structure at 2 GHz. used determine close ideal condition.

Design Investigation of Microstrip Patch and Half-Mode Substrate Integrated Waveguide Cavity Hybrid Antenna Arrays
In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
متن کاملEffective-index method and coupled-mode theory for almost-periodic waveguide gratings: a comparison.
Contradirectional propagation through active, first-order, almost-periodic, corrugated waveguide gratings is analyzed by using both coupled-mode theory and a combined effective-index/impedance-matching matrix technique. For TE-mode operation, which is near the first-order Bragg wavelength, the equivalence of the two techniques is analytically demonstrated for shallow surface corrugations.
متن کاملFrozen and broadband slow light in coupled periodic nanowire waveguides.
We develop novel designs enabling slow-light propagation with vanishing group-velocity dispersion ("frozen light") and slow-light with large delay-bandwidth product, in periodic nanowires. Our design is based on symmetry-breaking of periodic nanowire waveguides and we demonstrate its vailidy through two- and three-dimensional simulations. The slow-light is associated with a stationary inflectio...
متن کاملSize Effect in Waveguide Coupled Whispering Gallery Mode Disk Resonators
We investigate the bound and evanescent fields of the optical whispering gallery modes which are supported by a toroid microcavity and which may be used for a wide range of applications. Results of simulations using finite-difference time domain solutions of Maxwell’s equations are compared with semi-analytical solutions based on coupled mode theory. Key parameters such as resonance frequencies...
