In this letter, a novel transition from microstrip (MS) line to empty substrate-integrated waveguide
(ESIW) with tapered artificial dielectric slab matrix in compact size is proposed. ESIW …

In this Letter, a novel empty substrate‐integrated waveguide (ESIW) phase inverter (PI)
applied in millimetre‐wave has been proposed. ESIW PI, based on the structural symmetry …

This paper proposes an intelligent optimization clustering strategy based on partial order
clustering to address the issue of conditional clustering, presenting a novel higher-order …

In this letter, a novel 3-D empty substrate integrated waveguide (ESIW) phase shifter with
equal length has been proposed. The vertical transitions have been introduced into 3-D ESIW …

Background: China experiencing an increasing HIV epidemic among men who have sex with
men (MSM), and unprotected anal intercourse (UAI) has played a key role in this process. …

Due to uncontrollable influences of the manufacturing process and different construction
environments, there are significant challenges to extracting accurate positioning points for the …
