|Title:||Left-handed material effects on waves modes and resonant frequencies: Filled waveguide structures and substrate-loaded patch antennas||Authors:||Xu, W.
|Issue Date:||2005||Citation:||Xu, W., Li, L.-W., Yao, H.-Y., Yeo, T.-S., Wu, Q. (2005). Left-handed material effects on waves modes and resonant frequencies: Filled waveguide structures and substrate-loaded patch antennas.

By analyzing theoretically we find that the sizes of these equipments can be greatly reduced by using multi-block (which may include both double positive and double negative material) dielectric materials. In addition, the sizes of patch antennas are no longer proportional to the working frequency but roughly to the ratio of the thicknesses of dielectric slabs. Still some new modes in both waveguide and patch antennas are found, and by working at the new modes the bandwidth of the patch antenna can be dramatically increased.||Source Title:||Journal of Electromagnetic Waves and Applications||URI:||http://scholarbank.nus.edu.sg/handle/10635/56486||ISSN:||09205071||DOI:||10.1163/156939305775570459|
