Most existing space solar power concepts place one or more power stations in geosynchronous Earth orbit (GEO). However, due to the limited availability of GEO orbital slots, it may not be feasible to locate a power station in GEO. To overcome this li

We describe the application of an iterative research and development/system engineering process being utilized in the Caltech Space Solar Power Project (SSPP). We begin with a brief description of the SSPP approach to achieving a viable space solar p

Airglow due to upper atmospheric molecular emissions has been known since the late 1960's. Recent interest in extending high altitude low light imaging capability has created an interest in exploiting the airglow phenomenon. We discuss the feasibilit

This paper describes the theory of design, operation, and testing of a tunable MWIR Fabry-Perot interferometer operating in low orders. This device is called the agile bandpass tunable filter (ABTF) due to the fact that the spectral bandwidth can be

The agile bandpass tunable filter (ABTF) is a new instrument with variable resolution and center wavelength that allows MWIR and LWIR infrared cameras to recognize spectral images that are characteristic of specific materials, including gases. Benefi

We present the results of experiments aimed at improving the lifetime (longevity) of Si photoconductive semiconductor switches (PCSS). Because damage at the metal-semiconductor interface is the primary damage mechanism in most PCSS, we have tested di

This paper describes the performance of a broadband (0.3-10 GHz) cavity backed TEM horn with an exponential flare in two planes. The antenna pattern was measured using a pulsed source and found to have a 3 dB width of 50 deg. The two-way transfer fun
