Experiments on a Dual-Frequency, Harmonic, Magnetically Insulated Line Oscillator

Magnetically insulated line oscillators (MILOs) are crossed-field devices that generate high-power microwaves at the design frequencies without the use of external magnets. We present experimental data that demonstrates operation of a dual-frequency, Harmonic, Magnetically Insulated Line Oscillator (HMILO). This harmonic operation occurs in L-band (~1 GHz) and S-band (~2 GHz).
