Circularly polarized metasurface antennas
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012We present theory, design process and numerical results relevant to a X-band isoflux circularly polarized antenna for LEO satellite platform. The device is based on a metasurface made of a texture of small patches on a grounded dielectric slab. An in-plane feeder excites a surface wave on the metasurface that transforms it into a leaky wave The final ...

Circularly Polarized Equalizer Networks
IEEE Transactions on Microwave Theory and Techniques, 1974Characteristics of the cross slot coupling aperture applicable to circularly polarized equalizer networks is presented. This coupling mechanism is analyzed and experimental results indicate good agreement between theory and practice. Extension of the single-cavity unit to multiple direct-coupled dual-mode equalizer networks is also discussed.

A Circularly Polarized Maser Oscillator
Journal of Applied Physics, 1963The frequency stability of a circularly polarized solid-state paramagnetic maser oscillator has been observed with the objective of obtaining the information needed to construct a frequency standard with a broad microwave spectral line. The beat frequency between two such masers by using ruby can be made almost free from the variation of the static ...

[7] Circularly polarized luminescence
1978Publisher Summary This chapter focuses on circularly polarized luminescence. It investigates specifically how it is measured and what it may reveal about the molecules producing it. The occurrence of circularly polarized light in the luminescence of chiral molecules can be rationalized in terms of the known correspondence between absorption and ...
