摘要

表面等离子体，特别是多米诺等离子体已被证明是太赫兹波导的理想条件。然而，文献中对该技术的散热器没有足够的重视。在本文中，我们提出使用密集的介电基板来获得具有宽带和恒定辐射特性的漏波天线。为了提供我们提议的潜力的初步结果，我们研究了一种具有非常有前途的特性的微波设计，即-15dB的极低旁瓣电平(SLL)和低交叉极化(在所有方向上-30dB，在主平面上可以忽略不计)。

On the use of surface plasmons for the design of WB leaky ave antennas

Surface Plasmons and particularly Domino Plasmons have demonstrated to present ideal conditions for THz waveguides. However radiators for this technology had not enough attention in the literature. In this paper we propose the use of dense dielectric substrates to obtain a leaky wave antenna with broadband and constant radiation properties. In order to provide preliminary results of the potential of our proposal a design in the microwave regime has been studied with very promising properties, i.e. very low Side Lobe Level (SLL) of -15dB and low cross-polarization (-30dB in all the directions and negligible in the main plane).
