Introduction
I currently work at School of Electrical Engineering and Computer Science of KTH. I did research in RF microwave circuit, low phase noise oscillators, microwave filters, SIW structures, multi-mode resonators, microwave power amplifier and metamaterial absorbers. I proposed new transition for multilayer oscillators.

Article
Full-text available
In this article, we report for the first time on a low-loss compact platform that enables the integration of H-and E-plane rectangular waveguide subsystems enabled by 90 $^{\circ}$ polarization rotation of rectangular waveguide sections on a silicon-micromachined chip. The proposed platform offers unprecedented design flexibility for a 2.5D fabric...

This paper presents a novel design of a full-band E-plane waveguide bend for direct flange-to-chip connection. The proposed E-plane bend concept is validated with a reduced-height bend prototype designed for standard WR-3.4 waveguide flange-to-chip connection, fabricated by silicon micromachining, and characterized by de-embedding the S-parameters...

In this article, we present an ultra-narrowband silicon-micromachined bandpass filter with a wide and high-rejection stopband. The proposed filter uses high- $Q$ factor $\text{TM}_{330}$ mode resonators. To avoid near-passband spurious resonances typically associated with higher order modes, a novel method of arranging the positions of the coupl...

In this letter, triangular-cavity bandpass filters are investigated in stackable multilayer technologies in order to achieve highly compact designs with reduced fabrication complexity. The triangular-shaped cavities are first introduced in the form of singlets and then expanded on as a novel method for achieving a quasi-triplet filter response, whe...

This paper presents a novel single-layer dual band-rejection-filter based on Spoof Surface Plasmon Polaritons (SSPPs). The filter consists of an SSPP-based transmission line, as well as six coupled circular ring resonators (CCRRs) etched among ground planes of the center corrugated strip. These resonators are excited by electric-field of the SSPP s...

In this study, a reconfigurable triple-bandtriple-mode substrate integrated wave-guide filter is designed and fabricated in the C-band spectrum. A novel and simpli-fied design procedure based on analyticalequationsisproposed.Thefilterdesignalso benefits from a reconfigurable structure, using metallic via holes as perturba-tion, allowing wide-band s...

Because of exhibiting extraordinary features, metamaterial absorbers have captured considerable attention in recent years, especially at visible frequencies. In this paper, a new design of a metamaterial-inspired perfect visible absorber (MIPVA) is investigated, which exhibits ultra-broadband, polarization-independent, and wide-angle performances....
