Unique electrodynamic response of graphene implies a manifestation of an unusual propagating and localised transverse-electric (TE) mode near the spectral onset of interband transitions. However, excitation and further detection of the TE mode supported by graphene is considered to be a challenge for it is extremely sensitive to excitation environment and phase matching condition adherence. Her...

[1] Green’s function analysis of ideal hard surface circular waveguides is proposed with application to excitation and scattering problems. A decomposition of the hard surface waveguide into perfect electric conductor and perfect magnetic conductor waveguides allows the representation of dyadic Green’s function in terms of transverse electric (TE) and transverse magnetic (TM) waveguide modes, r...

We describe an experimental and theoretical characterization of rectangular resonant cavities integrated into parallel-plate waveguides, using terahertz pulses. When the waveguide is excited with the lowest-order transverse-electric mode, these cavities exhibit resonances with narrow linewidths. Broadband transmission spectra are compared with the results of mode-matching calculations, for vari...

Turn-oo transients in current-modulated weakly-index-guided vertical-cavity surface-emitting lasers (VCSELs) are analyzed by using a model that takes into account all the transverse modes supported by the waveguide. Turn-oo transients strength is maximum for the current at which the VCSEL enters the multi-transverse-mode regime. Their strength signiicatively decreases for the multi-mode regime ...

Presented is a review of recent work by the authors in which the lowestorder transverse-electric (TE1) mode of a parallel-plate waveguide (PPWG) is used for terahertz (THz) applications. This work adds a new dimension to the multitude of diverse THz applications made possible by PPWGs. Using the TE1 mode, demonstration is presented of an ultra-low loss THz waveguide, a highly sensitive microflu...

We demonstrate subwavelength bidirectional grating (SWG) coupled slot waveguide fabricated in silicon-on-sapphire for transverse electric polarized wave operation at 3.4 μm wavelength. Coupling efficiency of 29% for SWG coupler is experimentally achieved. Propagation loss of 11  dB/cm has been experimentally obtained for slot waveguides. Two-step taper mode converters with an insertion loss of ...

Recently Bo E. Sernelius [Phys. Rev. B 71, 235114 (2005)] investigated the effects of spatial dispersion on the thermal Casimir force between two metal half spaces. He claims that incorporating spatial dispersion results in a negligible contribution from the transverse electric mode at zero frequency as compared to the transverse magnetic mode. We demonstrate that this conclusion is not reliabl...

This paper outlines the RF design of the CLIC (Compact Linear Collider) 30 GHz main linac accelerating structure and gives the resulting longitudinal and transverse mode properties. The critical requirement for multibunch operation, that transverse wakefields be suppressed by two orders of magnitude within 0.7 ns (twenty fundamental mode cycles), has been demonstrated in a recent ASSET experime...

Symmetry-breaking and scattering cancellation were observed in the dark-mode resonance of dipolar gold nanoantennas (NAs) on glass substrates coupled with oblique incidence and total internal reflection. With the assistance of evanescent waves, the coupling efficiency was twice as strong when the incidence angle was larger than the critical angle. The Hamiltonian equation and absorption spectra...
