We investigated the usability of a trimming mechanism for varying an external quality factor (Q e ) in a hightemperature superconducting bandpass filter (BPF) using bulk resonators at around 5 GHz. The proposed trimming mechanism was composed of air

In this paper we study the following non-autonomous singularly perturbed Dirichlet problem: \begin{document}${\varepsilon ^2}\Delta u -u + K(x)f(u) = 0, \; u > 0\quad {\rm{in}}\; \Omega, \quad u = 0\quad {\rm{on}}\; \partial \Omega, $ \end{document}

We study concentration phenomena of the least energy solutions of the following nonlinear Schrodinger equation: \[ h^2 \Delta u - V(x) u + f( u ) = 0 \quad \text{in} \ \mathbb{R}^N, \ u>0, \ u \in H^1(\mathbb{R}^N)\,, \] for a totally degenerate pote
