This chapter presents case studies of various ways to perform dispersion engineering using
various slow‐wave structures (SWSs). Metamaterials (MTMs) with negative effective …

This thesis presents the theoretical and experimental investigation of the interaction of
metamaterial structures with electron beams for two applications: wakefield acceleration and …

Metamaterials are a new type of artificial materials engineered to have some exotic
properties such as Reversed Cherenkov radiation (RCR). Due to the attractive advantages …

This paper presents different Defected Waveguide Structures (DWS) towards monopole
antenna in Ultrawideband (UWB) frequencies. Monopole antenna is one of the potential …

In this paper, we present an S band improved metamaterial slow-wave structure (SWS),
which is in order to increase the bandwidth of the previously proposed metamaterial SWS. A …

This article presented defected waveguide structure (DWS) designs and characteristics with
microstrip‐fed circular monopole antenna for ultrawideband applications. Typically …

In this paper, we present an S band metamaterial-based sheet beam device. The
performance of this device is studied by particle-in-cell simulations and hot experiments. The …
