Broadband cloaking with volumetric structures composed of two-dimensional transmission-line networks
Pekka Alitalo, Olli Luukkonen, Juan Mosig +1
The cloaking performance of two microwave cloaks, both based on the recently proposed transmission-line approach, are studied using commercial full-wave simulation software. The cl…
Grounded Uniaxial Material Slabs as Magnetic Conductors
Olli Luukkonen, Constantin R. Simovski, Sergei A. Tretyakov
The objective of this paper is all-angle artificial magnetic conductor, i.e. artificial magnetic conductor that has stable magnetic-wall effect with respect to the incidence angle.…
Impedance-matched microwave lens
Pekka Alitalo, Olli Luukkonen, Joni Vehmas +1
A microwave lens with highly reduced reflectance, as compared to conventional dielectric lenses, is proposed. The lens is based on two-dimensional or three-dimensional transmission…
Transmission-line networks cloaking objects from electromagnetic fields
Pekka Alitalo, Olli Luukkonen, Liisi Jylhä +2
We consider a novel method of cloaking objects from the surrounding electromagnetic fields in the microwave region. The method is based on transmission-line networks that simulate…
A three-dimensional backward-wave network matched with free space
Pekka Alitalo, Olli Luukkonen, Sergei Tretyakov
A backward-wave slab based on a capacitively and inductively loaded three-dimensional transmission-line network is designed in such a way that impedance-matching with free space is…
Microstrip antenna miniaturization using partial dielectric material filling
Olli Luukkonen, Pekka Ikonen, Sergei Tretyakov
In this paper we study microstrip antenna miniaturization using partial filling of the antenna volume with dielectric materials. An analytical expression is derived for the quality…
