Design of Compact Bandpass Filters Using Novel Dual-Mode Dielectric Patch Resonator

IEEE Access, 2018
This paper introduces a new dual-mode dielectric patch resonator (DPR), which consists of a thin square dielectric patch with high permittivity and a low-permittivity substrate with bottom ground plane.

Slot coupled dual-mode patch filters

Electronics Letters, 1996
A configuration for the realisation of extracted pole planar elliptic function filters is proposed. The new filter configuration consists of chamfered patches in a microstrip assembly which are coupled by a slot. The two degenerated modes that can exist in a two-dimensional square resonator are slightly shifted in resonance frequency.

Design and Characterisation of Dual-Mode Suspended-Substrate Stripline Filter

, 2018
A new design technique of a dual-mode ring-resonator suspended-substrate stripline filter is reported here to achieve low passband insertion loss, high quality factor, and good spurious response. A fourth-order bandpass filter was designed and fabricated

Dual Mode Polarizing Pellicle

Journal of the American Society of Questioned Document Examiners, 2008
This article describes techniques for using an angled glass pellicle to merge the path of light reflected from a sample with the line of view, permitting glare-angle lighting/observation view normal to the surface. Among other applications, reflective properties of ballpoint and some other writing inks, observed under such conditions, may permit ...
