IEEE Transactions on Plasma Science, 2012 We propose exciting two modes concurrently inside a reltron's modulating cavity to increase the microwave power generated. From the harmonic components of the beam, we demonstrate that a multiharmonic beam has a higher peak and steeper gradient compared to a single-harmonic beam.

Open University Center of the Pontifical Javeriana University, Colombia
International Review of Research in Open and Distributed Learning, 2002 According to Garcia Canclini (1990) there is the assumption that Colombia is a hybrid society. Upon this standpoint, and within a traditional higher education structure characterized by being fundamentally conventional or campus based, the Open ...

Dual-Mode Large-Mode-Area Multicore Fiber With Air-Hole Structure
IEEE Photonics Journal, 2019 A novel dual-mode large-mode-area multicore fiber with air-hole structure, which is a quasi-37 core structured fiber with 20 air holes and 17 cores, is proposed in this paper.

Multistage depressed collector for dual mode operation [PDF]
, 1981 A depressed collector which captures the spent electrons of a microwave transmitting tube at high efficiency in both high and low power modes of operation is described. The collector comprises entrance and end electrodes, the end electrode having a spike

Generalized duality between local vector theories in $D=2+1$ [PDF]
, 2006 The existence of an interpolating master action does not guarantee the same spectrum for the interpolated dual theories. In the specific case of a generalized self-dual (GSD) model defined as the addition of the Maxwell term to the self-dual model in $D ...

Topological modes in dual lattice models [PDF]
Physical Review D, 1995 Lattice gauge theory with gauge group $Z_{P}$ is reconsidered in four dimensions on a simplicial complex $K$. One finds that the dual theory, formulated on the dual block complex $\hat{K}$, contains topological modes which are in correspondence with the cohomology group $H^{2}(\hat{K},Z_{P})$, in addition to the usual dynamical link variables.

Mechanisms of dual-wavelength dissipative soliton mode-locking in net-normal dispersion fiber lasers
Results in Physics, 2022 Dual-wavelength mode-locked fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy. However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still
