Abstract :
A planar inter-digital type slow-wave structures is proposed for forward first-space-harmonic operation. The proposed structure supports hybrid (even and odd) modes. The analysis of the proposed structures is carried out using CST-Microwave studio for the mode analysis and slow-wave characteristics (dispersion and interaction impedance characteristics) at W-band. Fabrication and cold test measurement of the structure is in progress and the measured results will be presented at the time of conference.
