One-Kind Hybrid Power Means of the Two-Term Exponential Sums and Quartic Gauss Sums

open access: yesJournal of Mathematics, 2021
The main purpose of this article is using the analytic methods and the properties of the classical Gauss sums to study the calculating problem of the hybrid power mean of the two-term exponential sums and quartic Gauss sums and then prove two interesting linear recurrence formulas. As applications, some asymptotic formulas are obtained.

Metal-Metal Terahertz Quantum Cascade Laser with Hybrid Mode Section [PDF]

open access: yes, 2015
A hybrid mode section is integrated into the end of the metal-metal (MM) waveguide of a terahertz (THz) frequency quantum cascade laser (QCL) by removing sub-wavelength portions of the top metal layer. This allows a hybrid mode to penetrate into the air,
