The study of the modal spectrum of canonical closed waveguides is a basic topic in any course of electromagnetics or microwave engineering. However, surface-wave modes and leaky-wave modes in open waveguides are not yet so well known in the academic environment. Nevertheless, this study is necessary, since novel open dielectric waveguides have been proposed for millimeter-wave and optical electronics in order to reduce the conductor losses. Therefore, the comprehension of the phenomenon of leaky-wave modes and behavior is indispensable for any future microwave engineer, who has to work with the new millimeter-wave and optical technologies. This program constitutes the first tool explicitly conceived to help the teaching of the working principles of open dielectric guides loaded with printed circuits, and the associated practical leaky-wave antennas (LWAs). The code can be a very good supplement to understand how practical leaky-wave antennas work, after a basic theoretical understanding of leaky waves has been first obtained. From the appearance of leaky-wave modes in open waveguides to the design of a backward-to-forward leaky-wave antenna, some simple and very clarifying step-by-step exercises are presented to illustrate these not-so-well-known concepts. Although the program refers to a specific type of open dielectric guides (laterally-shielded, top-open, stub-loaded, rectangular dielectric waveguides with planar perturbations), the results are applicable to any open dielectric guide, helping to teach the basic theory and topics relating to leaky- and surface-wave modes in uniform and periodic structures KW - Teoría de la Señal y las Comunicaciones KW - Guía de onda dieléctrica cargada KW - Guía de onda dieléctrica no radiativa KW - Circuito impreso KW - Antena de guía de onda KW - Fuga de ondas KW - Antena de fuga de ondas KW - Ingeniería asistida por ordenador KW - Instrucciones asistidas por ordenador KW - Dielectric loaded waveguide KW - Non homogeneously loaded waveguide KW - Non radiative dielectric waveguide KW - Printed circuit KW - Waveguide antenna KW - Wave leakage KW - Leaky-wave antenna KW - Computer aided engineering KW - Computer aided instruction KW - Guía de onda no homogéneamente cargada LA - eng PB - IEEE Antennas and Propagation Society ER -
