This paper presents an investigation into the use of photoconductive silicon for controlling microwave circuits. Initial experiments show that significant changes in the S21 characteristics of a 9 GHz silicon end coupled filter can be implemented. The results are compared against an equivalent copper conductivity.
This paper presents the first results of the fabrication and characterization of a biological sensor based on two complementary parts. A microfluidic channel along with a micromachined stop-band filter are used to detect the type of fluid which flows beneath the electronic circuit. The tridimensional (3D) structure of the microstrip technology is integrated using SU8 material which thus supports the...
A single-mode ring resonator which is fed along one of its quarter-wavelength sides is presented. The resonator's response presents transmission zeros whose frequencies can be modified by adjusting the line impedance of the ring and the coupling level of the feeding coupled-line. The proposed topology introduced much simpler bandpass filter configuration and reduced the number of control parameters...
A novel ring resonator which is fed along one of its quarter-wavelength sides is presented. The resonator's response presents a single-mode resonant frequency with a transmission zero at both sides of its passband. Two such resonators are proposed to be combined in series to result in a 3rd order bandpass response with a good out-of-band rejection level. The resonator and filter are simulated and...
