While chemoselectivities in Pd0 -catalyzed coupling reactions are frequently non-intuitive and a result of a complex interplay of ligand/catalyst, substrate, and reaction conditions, we herein report a general method based on PdI that allows for an a priori predictable chemoselective Csp2 -Csp2 coupling at C-Br in preference to C-OTf and C-Cl bonds, regardless of the electronic or steric bias o...
Novel High-Selectivity Dual-Band Substrate Integrated Waveguide Filter with Multi-Transmission Zeros
A novel dual-band filter based on substrate integrated waveguide (SIW) is presented in this paper. The proposed filter is composed of two filters with different center frequencies and bandwidths, where they share input and output ports with source-load coupling using rectangular SIW cavity structure. Multi-transmission zeros have been obtained through electrical coupling between the source and ...
A simple bulk model of electron-phonon coupling in metals has been partially successful in explaining experiments on metal films that actually involve surfaceor other low-dimensional phonons. However, by an exact application of this standard model to a semi-infinite substrate with a free surface, making use of the actual vibrational modes of the substrate, we show that such agreement is fortuit...
This paper presents the modeling and simulation of simultaneous switching noise (SSN) in on-chip power distribution networks (PDN). The circuit model of power buses over lossy silicon substrate is extracted as frequency dependent RLGC elements. The coupling between conductors on adjacent layers is represented as coupling capacitors. Accurate analytical formulae are derived to extract the RLGC t...
This paper summarizes the objectives and some early results of the ESPRIT project 29260 BANDIT. It is a 3 year project that started in September 1998. Coordinating partner is IMEC and the other partners are K.U.Leuven and Ericsson Radio Systems (ERA). The goal of BANDIT is to develop a general design and test methodology for embedding high-speed analog/digital converters (ADCs) on large digital...
The existing catalytic enantioselective cross-dehydrogenative coupling of cyclic amines predominantly focused on reactive N-aryl tetrahydroisoquinolines, which typically suffered from limited substrate generality and synthetic utility, and required the use of metal catalyst. Herein, a metal-free catalytic enantioselective cross-dehydrogenative coupling of N-carbamoyl cyclic amines and aldehydes...
An increasingly urgent topic for the realization of densely packed (mixed signal) integrated circuits is prevention of cross-talk via the substrate. Due to decreasing distances between components and increasing operating frequencies, the coupling between components and/or circuit blocks becomes stronger and affects the circuit behaviour more and more. This paper proposes a Boundary Element Meth...
