Walter details two main types of waves used for radiation:
Originally published in 1965 by McGraw-Hill, Walter's work was born out of necessity following . The military needed "flush" antennas—antennas that could be built into the skin of high-performance aircraft to avoid aerodynamic drag—which required moving away from traditional resonant stubs and toward traveling wave structures like slots and dielectric rods.
