This letter presents the design of a customizable 3-D printed insert that can be placed into a standard WR-90 waveguide to realize an inline waveguide filter. These 3-D printed inserts have a significantly lower manufacturing cost and turnaround time compared to the conventional solid copper or bronze waveguide. A two-pole X-Band filter insert has been designed to demonstrate this unique approach...
An efficient fully automated EM-level design framework is implemented using Matlab, Sonnetlab toolbox and Sonnet EM simulator for the design of different type of sequentially coupled resonator planar filters. The proposed implementation integrates the space mapping technique and reflected group delay method to achieve fast and reliable EM-based filter design. In this paper, two design examples are...
In the area of home security and protection, vision-based home automation systems (HAS) play a significant role. In this paper, we present the design and implementation of a smart HAS with incorporated intrusion detection to minimize damages caused by burglary. In addition, the proposed HAS integrates a web server to home appliances in order to remotely access and control their status. Intrusion detection,...
A novel 8-mask fabrication process for the integration of Low Temperature Superconducting (LTS) niobium (Nb) RF circuits with gold-based RF MEMS switches is proposed. A fixed and a tunable 3-pole bandpass filter (BPF) are fabricated implementing the new Nb-based fabrication process. The tunable BPF includes nine dc-contact RF MEMS switches. The center frequency of the tunable BPF shifts from 10 GHz...
Power systems in large geographic environments experience diverse weather phenomena. Due to spatial separation and economic diversification, load centres will exhibit differing electrical demand. This diversity of weather and electric loads proves challenging for load forecasters using a single aggregate model. In such systems, aggregate response of these load centres cannot be properly analyzed by...
Today's microwave systems can benefit greatly from the use of tunable filters, which have some distinct advantages over traditional microwave filters and are continuously being improved. This paper presents an approach for designing tunable filters with a minimum number of tuning elements. While the majority of published work in this area uses synchronous tuning, the proposed approach is based on...
