“…With this prototype the main limitations of the rover were overcome, this is that not bumpy areas can be observed. This is a possible alternative to the rover, but due to the atmospheric conditions on Mars, the airplane should be as small and light as possible [34,35].…”

Agradecimientosos vaya muy bien con Gargamel aunque ya me dijisteis que cerró el café. ¡Qué pena!. Muchas gracias a mi director de estancia Yi Huang y Chaoyun Song, por su generosidad al haberme acogido en su grupo.Ellen, fue muy curioso cuando por casualidad estuvimos las dos viviendo en Reino Unido a la vez. Gran viaje lleno de aventuras por las tierras de Robin Hood. El Castillo nos dejó sin palabras... Espero que nos veamos pronto, tengo que ir por Holanda. Muchas gracias por todo, me has ayudado mucho a mejorar mi nivel de inglés. Tú, en cambio, el español lo dominas, ¡eres increíble con los idiomas! María, aprendí mucho de ti en sincro, primero mi entrenadora y luego compañera. Una pena que te fueses lejos. En ese año y medio aprendí muchísimo de ti, a cómo torear las dificultades y a disfrutar aunque nos lo pusieran difícil. Lo pasamos bien con nuestras niñas. Recuerdo cuando estabas embarazada y me dijeron que si yo había tenido ya el bebé, porque como estaba delgada... ¡Qué bonita es la inocencia! Es una de las cosas más bonitas de la vida.Muchas gracias a todos y espero que os leáis todos la tesis...

The objective of the present study is to investigate the feasibility of microwave power transmission to an airplane for future Mars observation. Airplane is a possibility of Mars observation with wide range and high resolution, compared to rover or satellite. Since the surface pressure of Mars atmosphere is much thinner than the Earth, weight reduction is essential to realize airplane flight on Mars. We therefore propose long-time flight on Mars by using microwave power transmission. We conducted terrestrial experiments of microwave power transmission to a prototype airplane. We developed a magnetron-based microwave transmitting system, the frequency of which was fixed with signal injection locking method. Rectennas (receiving antenna + rectifying circuit) were mounted on the prototype airplane for driving a propeller connected to an electric motor. Although autonomous flight was not successful yet, we demonstrated that the prototype airplane could fly by receiving the microwave power.

“…To make the space solar power system (SSPS) economically feasible that transfers electric power wirelessly via microwave to the earth after the sunlight generation on the geostationary orbit, a high-power microwave module capable of (1) few grams per unit power in the weight-power ratio and (2) 70% or higher in the DC-RF power conversion ratio, is required. [1][2][3][4][5][6][7][8][9][10][11][12][13] Magnetron is a competitive source satisfying both of the requirements, (1) to reduce launch costs and (2) to maximize energy utilization and to minimize thermal loss, among various microwave modules. [2,14] Because of such competitiveness, magnetrons have been widely adapted in various fields such as microwave ovens of home appliances, radars, communication, medical accelerators, generation of processing plasmas, industrial heating and chemical process intensification.…”

We demonstrate noise suppression and precise phase control of a commercial 2.45GHz magnetron aiming for wireless power transfer application. The impurity of the microwave spectrum was confirmed to be due to the switching frequency of 76kHz in the power supply. With the decoupling capacitor installed to the output of the high-voltage power-supply driving the magnetron, the spectral purity of the magnetron was significantly enhanced. And we achieved extreme precision in phase-control (peakto-peak 0.3°) for the high-power (1 kW) microwave magnetron by applying the phase locking loop to the noise-suppressed magnetron system.
