DOI: 10.1016/j.aim.2018.08.007
Abstract: Quasi-elliptic cohomology is a variant of elliptic cohomology theories. It is the orbifold K-theory of a space of constant loops. For global quotient orbifolds, it can be expressed in terms of equivariant K-theories. Thus, the… read more here.

DOI: 10.1049/el.2020.0200
Abstract: In this Letter, a novel filtering power divider with second-order quasi-elliptic bandpass response is proposed, which has two transmission zeros near to the passband for sharp frequency selectivity. In addition, it is featured by ultra-wide… read more here.

DOI: 10.1080/02726343.2017.1409489
Abstract: ABSTRACT This paper presents a quasi-elliptic wideband bandpass filter (QEWB-BPF) constituting a pair of lumped-element dual-resonance resonators (LE-DRRs) with mixed electric and magnetic coupling (MEMC). Two resonant modes of proposed LE-DRR can be controlled separately.… read more here.
