A three left-handed metamaterial unit cell antenna is presented in this article for ultrawideband applications. Each left-handed metamaterial unit cell is a combination of a modified octagonal split-ring resonator, an octagonal spiral resonator, a capacitance-loaded strip, and a wire in order to achieve a design that simultaneously exhibits both negative electrical permittivity and negative mag...

In the present paper a multilayered microstrip low pass filter using complementary split ring resonator is proposed. A design for prominent stop band characteristics with minimized ripples is presented, while maintaining the filter pass-band performance. By properly designing and integrating the complementary split ring resonators with the low pass filter, the proposed structure exhibit superio...

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...

Electro-optic switching of reflection and refraction is experimentally demonstrated in metasurface liquid crystal cell. Negative metasurface is fabricated by focused-ion-beam milling, and twisted nematic cells are constructed with complementary double-split ring resonator and V-shape slot antenna metasurface. By application of an external voltage, electro-optic switchings are achieved in reflec...

This paper aims to produce a high data capacity and miniaturized flexible chipless RFID tag based on the frequency signature using Modified Complementary Split Ring Resonator (MCSRR). The proposed 19 bits shifting technique consists of five slotted overlaying MCSRR with Different Width (MCSRR DW) structures dimension 48 mm × mm. structure is designed by (Polyethylene Terephthalate) PET substrat...

We propose a short period undulator based on the electromagnetic field pattern in THz-driven split ring resonator structure. An analytical model is developed that allows us to assess key performance parameters of and estimate emitted radiation spectrum. Different geometric configurations are compared detail using numerical simulations. A 100 MeV electron bunch with 5 pC charge shown emit narrow...
